chore: release v0.20.12

A SteppIR only covers part of the spectrum (a standard one is 20 m–6 m) but
can't report its own range, so the follow loop's existing out-of-range guard
(FreqMin/FreqMax) never engaged for it. Tuning the rig to a band the antenna
can't reach (e.g. 30 m) made the loop keep trying — the immediate cause of the
stuck TX interlock addressed in the previous commit.

Add a Tunable range (MHz) setting to the Antenna panel, wired into the SteppIR
adapter's Status().FreqMin/FreqMax so the follow loop skips out-of-range
frequencies entirely: no tune command, no TX inhibit. Defaults to 13–54 MHz
(20 m–6 m, the common model) when unset; widen the low edge for a 40 m-equipped
SteppIR. Ultrabeam is unaffected (it reports its own per-band coverage).

Keeps the last-commanded-freq deadband from the previous commit as a universal
safety net for any flaky-status case within the valid range.

+      "Fixed a motorized-antenna bug that could leave a FlexRadio permanently unable to transmit (‘Interlock is preventing transmission’). With a SteppIR whose status frequency reads intermittently (it flipped between the commanded frequency and its home value), the ‘follow the rig’ loop re-sent a tune command on almost every poll, and each command re-armed the ‘block TX while the antenna moves’ window — so the interlock never released. The follow loop now keys its deadband off the rig’s frequency (only re-tuning when the RADIO actually QSYs), immune to a flaky antenna status. Also dropped an ‘interlock set reason=’ command that SmartSDR rejects (it’s read-only) and only produced a harmless error line — the transmit-inhibit itself is unchanged and still holds TX safely while the elements move. New: a SteppIR ‘Tunable range’ setting (Settings → Hardware → Antenna, default 13–54 MHz = 20 m–6 m) — on a band outside it OpsLog leaves the antenna and TX completely alone, so tuning to 30 m on a 20 m–6 m SteppIR no longer tries to move it or touches the interlock.",
+      "New built-in award: The Helvetia 26 Award (H26) — the 26 cantons of Switzerland (USKA). Ships with the full canton reference list; matches the canton from the QSO's address or QTH, on HF, for Swiss (HB) contacts. Enable it in Awards and rescan to see your standings.",
+      "FlexRadio panel: the RECEIVE card is shorter again. All the noise controls added recently made it tower, so only the everyday ones — NB, NR, ANF — now stay visible; WNB and the SmartSDR v4 DSP block (NRL/NRS/NRF/ANFL and the AI/FFT RNN & ANFT) tuck behind a 'DSP' button you expand when you need them. The button carries a dot and highlights when one of the hidden controls is switched on, so nothing active is ever out of sight, and its open/closed state is remembered.",
+      "ADIF export can now pick exactly which fields to write. The global 'Export to ADIF' dialog gains a third choice, 'Choose fields…', alongside 'Standard ADIF fields' and 'All OpsLog fields'; and right-clicking selected QSOs adds 'Export selected — choose fields…'. The picker separates the official ADIF 3.1.7 fields (grouped by category) from OpsLog / non-standard tags actually present in your log, with All/None per group and a one-click reset to defaults. Your selection is remembered for next time.",
+      "Fixed 'Incorrect string value' (MySQL error 1366) when a QSO contained non-Latin characters — Cyrillic (Я), Polish ł, etc. — e.g. updating from QRZ. It happened when the shared MySQL database had been pre-created by the hosting panel as latin1, so OpsLog's tables couldn't store those letters. OpsLog now converts the database and its tables to utf8mb4 on connect (once, automatically), and everything stores correctly. Local SQLite logbooks were never affected.",
+      "NET Control: the on-air list now follows a mic-pass order you control instead of log time. A pinned '#' column numbers the round, ⬆⬇ buttons move the selected station up/down the queue, new check-ins join the end, and 'Log & end' advances to the next in line. The order is remembered per net. Header sorting is disabled on this list so a click can't shuffle the round.",
+      "The CW decoder (RX audio → text) is back, with a rebuilt decoding engine. The first version struggled on real signals; the new one adds a windowed tone detector, an adaptive dB envelope with noise squelch, two-way debouncing (a brief fade inside a dash no longer shatters it into dots), per-character dit/dah classification (even the first letter of an over decodes at any speed), and gap-fed speed tracking. It rides QSB, ignores QRM on other pitches, follows 12–40 WPM and sloppy hand keying — all proven by a synthetic-signal test suite. Tools → CW decoder (or the ear button): decodes while the mode is CW, with WPM/pitch/level display, pitch lock (follows the FlexRadio CW pitch automatically), and click-a-word to fill the callsign. Weak signals in heavy QRM remain hard — that's CW Skimmer territory — but clean-to-moderate signals now decode solidly.",
+      "Finished translating the Settings dialog: several panels that had stayed in English are now French too — the CW Keyer panel (and its long serial-engine paragraph removed for clarity), Password encryption, the ClubLog exceptions / Most Wanted blocks in General, and the External services tabs (HRDLOG, eQSL, LoTW, POTA).",
+      "Serial CW keyer: fixed the rig dropping to RX between words during a macro (PTT not held). On USB-serial interfaces like the Yaesu SCU-17 (CP210x), the previous method of driving the DTR/RTS lines would drop the held RTS (PTT) as soon as DTR (CW) toggled. OpsLog now drives the lines with the direct Win32 method N1MM/WSJT use (EscapeCommFunction), so RTS stays asserted for the whole transmission. 'Key PTT line' also defaults on for the Serial engine, and PTT / key-line / speed changes apply immediately without reconnecting the keyer.",
+      "New (Settings → General): show the ClubLog 'Most Wanted' rank in the entry-strip band matrix. When on, a 'MW #rank' pill appears next to the DXCC entity name (1 = the most wanted entity), coloured hotter the more wanted it is. The list is fetched from ClubLog and personalised to your callsign, refreshed daily.",
+      "Fixed the colour theme sometimes resetting to light after an update/relaunch: an update can clear the WebView's localStorage, and the fallback that restores the theme from the local settings database gave up after ~2.4s — occasionally too soon during the brief startup window before that store is ready. It now keeps retrying until the store actually answers, so a dark theme is reliably restored."

Avec une SteppIR dont la fréquence de statut se lit par intermittence (elle alternait entre la fréquence commandée et sa valeur de repos), la boucle de suivi renvoyait un ordre d'accord à presque chaque cycle, et chaque ordre réarmait la fenêtre « bloquer l'émission pendant que l'antenne bouge » — l'interlock ne se relâchait donc jamais. La boucle de suivi se base maintenant sur la fréquence de la RADIO (elle ne réaccorde que quand le poste change réellement de fréquence), insensible à un statut d'antenne erratique. Retrait aussi d'une commande « interlock set reason= » que SmartSDR refuse (champ en lecture seule) et qui ne produisait qu'une ligne d'erreur sans effet — l'inhibition d'émission elle-même est inchangée et protège toujours pendant le mouvement des éléments. Nouveau : un réglage « Plage accordable » pour la SteppIR (Réglages → Matériel → Antenne, défaut 13-54 MHz = 20 m-6 m) — sur une bande hors de cette plage, OpsLog laisse totalement l'antenne et l'émission tranquilles, donc passer sur 30 m avec une SteppIR 20 m-6 m ne tente plus de la bouger ni ne touche à l'interlock.",

Il tient le QSB, ignore le QRM sur d'autres tonalités, suit de 12 à 40 WPM et la manipulation humaine approximative — le tout prouvé par une suite de tests sur signaux synthétiques. Outils → Décodeur CW (ou le bouton oreille) : décode quand le mode est CW, avec affichage WPM/tonalité/niveau, verrouillage de tonalité (suit automatiquement le pitch CW du FlexRadio) et clic-sur-un-mot pour remplir l'indicatif.

+// Package cwdecode is a real-time CW (Morse) decoder: it turns a stream of
+// mono PCM samples into decoded text.
+//
+// This is the second generation of the decoder. The first one worked on clean
+// machine keying but fell apart on real signals; every stage below exists to
+// fix a specific failure of that version (and of naïve Goertzel decoders in
+// general):
+//
+//	audio ─ Hamming-windowed Goertzel bank ─ pitch lock ─ dB envelope with
+//	separate noise-floor / peak trackers ─ hysteresis slicer + SNR squelch ─
+//	DEBOUNCED mark/space stream ─ two-cluster dit/dah length tracking ─
+//	element / character / word segmentation ─ Morse table ─ text
+//
+// The fixes that matter, in order of impact:
+//
+//  1. Debounced transitions BOTH ways. The old decoder rejected too-short
+//     marks but not too-short SPACES, so a one-hop fade inside a dah (QSB,
+//     static crash) split it into two dits — the single biggest source of
+//     garbage on real signals. Here a state flip must persist for a glitch
+//     time (~0.3 dit) before it is committed; shorter flips are folded back
+//     into the surrounding element.
+//
+//  2. Two-cluster timing. Dit and dah lengths are tracked as two separate
+//     moving centres with the decision boundary at their geometric mean,
+//     instead of one EMA "dot length" that both classifies marks and is
+//     updated by that same classification (a feedback loop that spiralled to
+//     "all dits at 60 WPM" the moment it started mis-classifying). The
+//     inter-element gaps also feed the dit centre — spaces are timing
+//     evidence too, and hand keying is often more regular in its gaps than
+//     in its dits.
+//
+//  3. dB-domain envelope. Peak and noise floor are tracked in dB with
+//     asymmetric attack/decay, the slicer runs at 55%/38% of the span with
+//     hysteresis, and a minimum-span squelch (6 dB) keeps pure noise from
+//     keying at all. In the old linear-magnitude scheme weak signals lived
+//     in the bottom few percent of the scale and QSB swallowed them.
+//
+//  4. Windowed Goertzel. A Hamming window tames spectral leakage so a strong
+//     tone doesn't bleed across the whole bank and corrupt both the noise
+//     estimate and the lock choice.
+//
+// Kept from the first version because they were right: the pitch LOCK (decode
+// one tone, ignore QRM at other pitches), pitch targeting (follow the radio's
+// known CW pitch instead of searching — SetTarget), tiered acquisition
+// (strong signals lock on the first hop so their opening dit isn't eaten),
+// the floor frozen during key-down (a rising floor mid-dah fragments it), and
+// the end-of-over flush when the lock releases.
+//
+// Deliberately dependency-free and fed by plain []int16 so the whole pipeline
+// is unit-tested with synthetic signals (see cwdecode_test.go: clean keying at
+// several speeds, added noise, QSB fading, QRM on a nearby pitch, and a
+// noise-only squelch test).
+//
+// Honest expectations: on clean or moderately noisy signals this decodes
+// solidly; very weak signals in heavy QRM remain hard for any envelope
+// decoder — the tools that shine there (CW Skimmer, SDC) use probabilistic
+// sequence estimation on top. This stage is designed so such a layer could be
+// added later without touching the DSP.

+## Why doesn't a QSO count? — Test & Missing refs
+
+An award that matches nothing is the hardest thing to debug: the column is just
+empty, and you can't tell whether the QSO was out of scope, the field was empty,
+the rule looked in the wrong place, or the reference isn't on the list. Two tools
+answer that.
+
+### Test a callsign (award editor)
+
+In the **award editor** there's a **Test** box: type a callsign and OpsLog
+replays that award's rules against every QSO you have with that station and shows
+what happened, step by step — the exact same code path the real matcher uses, so
+what you see is what actually runs. For each contact it reports:
+
+- whether the QSO is **in scope** (and, if not, *why* — wrong DXCC, band, mode,
+  emission, or outside the valid-from/to dates);
+- each rule in turn (**primary**, then **Fallback 1, 2, …**), the **field value**
+  it scanned, the **candidates** it produced, which ones were **kept**, and which
+  were **rejected** (with the reason — e.g. "not on the reference list");
+- rules that were **skipped** because an earlier one already matched;
+- any **manual** reference you assigned by hand;
+- the final **result** — what the QSO counts for.
+
+This is the fastest way to fix a rule: if the primary scanned the wrong field, or
+a candidate was rejected as unlisted, the trace says so directly.
+
+### Missing refs (awards panel)
+
+For an award scoped to a DXCC entity (DDFM, WAS, RAC, WAJA…), the **Missing refs**
+view lists contacts that ARE in scope (right DXCC / band / mode / dates) **but
+where no reference was found** — so they don't count yet. Sort by a column, tick
+the matching contacts, and **assign the reference** to all of them at once (or
+click a row to open the QSO and fix the field). Recompute and the fixed contacts
+drop off the list. This is how you close the gaps a matcher can't fill on its own
+(a French QSO logged without its department, say).
