fix: convert MySQL logbook to utf8mb4 (fixes 1366 on Cyrillic/Polish)

A QSO with a non-Latin character (Cyrillic Я = \xD0\xAF, Polish ł, …) failed to
save on the shared MySQL backend with "Error 1366: Incorrect string value …
for column 'qso'.'address'". Cause: the database had been pre-created by a
hosting panel (o2switch/cPanel) as latin1, so OpsLog's CREATE DATABASE IF NOT
EXISTS … utf8mb4 was a no-op and every table inherited latin1 — which can't
store those letters, even over a utf8mb4 connection.

OpenMySQL now runs ensureMySQLUTF8MB4 after migrations: ALTER DATABASE to
utf8mb4 (for future tables) + CONVERT any table with a non-utf8mb4 text column
via an information_schema probe. Idempotent and cheap on a healthy DB (the probe
returns nothing → no ALTERs); best-effort so a charset issue never blocks
logbook access. SQLite is unaffected.

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.",

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.",

The frame layout is now detected from the data itself, so the 7300 (and other single-scope Icoms) render correctly, in both center and fixed modes. The IC-7610/9700 are unaffected.",

La disposition des trames est maintenant détectée à partir des données elles-mêmes, donc le 7300 (et les autres Icom mono-scope) s'affichent correctement, en mode centre comme en fixe. Les IC-7610/9700 ne sont pas affectés.",

+// 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.
