docs(changelog): move log-viewer entry to 0.23.6 (0.23.5 already released)

The viewer fetched only the last 256 KB (~1600 lines) of opslog.log. During a
busy trace the oldest lines scrolled out of the window while the operator was
still reading them. Raise the tail to 1 MB (~6500 lines); the backend already
allows up to 4 MB.

+# ACOM built-in ATU — what we know, and why OpsLog does not drive it
+
+Session of 2026-08-02 on F4BPO's friend's **ACOM 500S**, serial link, telemetry
+trace. Written down so nobody repeats the work. **Conclusion first: the tuner
+cannot be started over the serial link, and the attempt to work around that was
+abandoned.**
+
+## The tuner is PA state 8
+
+Frame byte 3's high nibble is the PA status. ACOM's own list (recovered by the
+ACOM-Controller project) has no entry for 8; it is the antenna tuner. Confirmed
+twice, front-panel TUNE, with the byte-level trace running:
+
+```
+14:47:20.745  state 8 step 0   ← TUNE pressed. err=FF
+14:47:22.588  operator keys a carrier (FT-891, FM, 31 W, 3.6358 MHz)
+14:47:24.006  state 8 step 2
+14:47:25.201  state 8 step 4
+14:47:27.457  state 8 step 5
+14:47:30.092  state 5 STANDBY  ← accord finished
+```
+
+Byte 3's **low** nibble is a step counter through the accord: `0 → 2 → 4 → 5`.
+Step 0 means *armed, waiting for RF* — in the first of the two runs the
+amplifier sat there **30 seconds** untouched before the operator transmitted.
+
+`paStatusNames[8] = "TUNE"` in acom.go is the only thing kept from all of this.
+
+## The command does not exist in the state-command family
+
+Every action byte of `55 81 08 02 00 XX 00 CHK` was tried, each one from a
+**verified** STANDBY (an earlier sweep was worthless because its second code
+parked the amp in SERVICE, where it silently refuses everything — 17 false
+negatives). Result:
+
+| byte | effect |
+|------|--------|
+| 0x01, 0x02 | **reboot the amplifier** — it prints `AMPLIFIER: ACOM 500S / HELLO ME…` |
+| 0x04 | → SERVICE (state 4) |
+| 0x05 | → STANDBY (state 5) |
+| 0x06 | → OPERATE (state 6) |
+| 0x0A | → OFF (state 10) |
+| 0x03, 0x07..0x09, 0x0B..0x18 | nothing, state unchanged |
+
+The action byte **is** the target PA state — four independent confirmations.
+Which makes 0x08 the obvious candidate for TUNE. **It was tried, from a verified
+STANDBY, and does nothing.** State 8 is reachable from the front panel only.
+
+Going further would mean varying the other bytes of the frame. That is a large
+space, and 0x01/0x02 prove that bad values reboot a 500 W amplifier. Not worth
+it.
+
+## The workaround that was built and removed
+
+Since the amp waits, armed, for a carrier, OpsLog could watch for state 8 and
+supply one: memorise the mode, drop the power, switch to FM, key the PTT, wait
+for state 8 to clear, unkey, restore. It was implemented (`acomtune.go`, opt-in,
+Settings → Amplifier) and **removed** after the first hardware test:
+
+- the power change did not take effect, and
+- **the PTT was not released when the tune finished.**
+
+A logger that can leave a transceiver keyed is not acceptable, and the whole
+thing was scaffolding around a protocol we do not actually control. Removed at
+the operator's request: *"je veux qu'OpsLog soit solide et ça c'est de la
+bidouille."*
+
+If it is ever revisited, the unexplained part is why the tune-finished detection
+did not fire — `anyAcomTuning()` polled `StateRaw == 8` every 200 ms and should
+have seen the drop to STANDBY. Suspect the status snapshot, not the amplifier.
+
+## Loose ends worth knowing
+
+- **Frame byte 6 is a multiplexer.** The tail of the frame changes meaning with
+  it: `0x93` = bytes 48/49 carry the TX frequency in kHz (`62 1B` = 7010 while
+  the rig was on 7.010 MHz), `0x9D` = something else. Byte 70 looked like a
+  tuner flag for a while purely because of this — it toggles on its own several
+  times a minute. Do not read tail bytes without checking byte 6.
+- **Byte 5 bit 0x80 alternates frame to frame.** It is a sequence/parity bit,
+  not a command acknowledgement.
+- **Byte 66 (the error code) shows 0x14 / 0x8E / 0x69 / 0x0F during a normal
+  tune and during transmission.** `errText` renders those as "ERROR — see
+  display" and "Remove drive power", so an ACOM operator probably sees a false
+  alarm. This was never confirmed with the amplifier in OPERATE (it was in
+  STANDBY throughout, where drive genuinely is an error) — worth a look with a
+  clean log before touching the table.

+## Consequences
+
+- **A free QRZ account can never fill the locator, the coordinates, the zones
+  or the e-mail.** If someone reports a logger doing it on a free account, they
+  are either using HamQTH (free, returns a 6-character `grid`) or they hold an
+  XML subscription without realising it — the QRZ.com account and the "XML
+  Logbook Data" subscription are sold separately. `SubExp` in the session block
+  settles it in one request.
+- **Profile edits take a few minutes to reach the XML feed.** Changing the grid
+  on the website and looking the callsign up immediately returns the OLD value,
+  which looks exactly like a stale cache. Re-test after a few minutes before
+  suspecting the logger. (This cost an hour on 2026-08-02.)
+
+## Fields OpsLog does not use yet
+
+`qrz.go` maps call, name, addr1/2, zip, state, county, country, grid, lat, lon,
+dxcc, cqzone, ituzone, cont, email, qslmgr and image. Left on the table:
+
+- **`geoloc`** — `user` when the operator entered the position by hand, versus a
+  geocoded value derived from the postal address. This is a direct statement of
+  how much the coordinates and the locator can be trusted, and it is exactly
+  the question the grid-precision rule in App.tsx tries to answer by comparing
+  string lengths. Worth wiring if the locator ever misbehaves again.
+- **`eqsl` / `mqsl` / `lotw`** — the station's QSL preferences as flags, more
+  reliable than parsing the free-text `qslmgr`.
+- `nickname` / `name_fmt`, `class`, `moddate`, `bio`.
