- Make stopAprs() async and await backend stop completion before
re-enabling the Start button, preventing race where a late stop
request kills newly started processes
- Add cache-buster param to EventSource URL to prevent browser
SSE connection reuse between stop/start cycles
- Capture aprs_active_device locally in stream_aprs_output so the
old thread's finally block doesn't release a device claimed by
a new session

Replace hardcoded rtl_fm with SDRFactory abstraction layer so WeFax works
with any supported SDR hardware, matching the pattern used by APRS and
other modes. RTL-SDR direct sampling flag preserved for HF reception.

The default 1 MHz sample rate was too low for SatDump's meteor_m2-x_lrpt
pipeline, causing NOSYNC and 0.000dB SNR. Bumped to 2.4 MHz (SatDump
recommendation) and wired up the WEATHER_SAT_SAMPLE_RATE config value
so it actually gets passed to decoder.start() from both the auto-scheduler
and manual start route.

Fix silent failure when starting without station/frequency selected by
flashing amber on status text and dropdowns. Add auto-capture scheduler
that uses fixed UTC broadcast schedules from station data to
automatically start/stop WeFax decoding at broadcast times.

Implement HF radiofax decoding with custom Python DSP pipeline
(rtl_fm USB → Goertzel/Hilbert demodulation), 33-station database
with broadcast schedules, audio waveform scope, live image preview,
and decoded image gallery. Amber/gold UI theme for HF distinction.

- Remove profiles: [basic] from intercept service so docker compose up -d
works without --profile flag (fixes breaking change for existing deployments)
- Add missing Any import to routes/acars.py and routes/vdl2.py
- Reset last_message_time to None in ACARS and VDL2 clear endpoints
- Restore 131.725 and 131.825 to default ACARS frequencies (major US carriers)
- Copy VDL2 ACARS enrichment fields to top-level data dict instead of mutating
nested acars_payload (consistent with ACARS route pattern)

The shared audio queue (maxsize reduced from 80 to 20) was not flushed
when the monitor frequency changed — only when the monitor was disabled.
This caused up to 4 seconds of stale old-frequency audio to play after
clicking to tune, making click-to-tune appear non-functional.
Now flushes the queue whenever the VFO frequency changes, so audio at
the new frequency begins within ~50ms (one FFT frame).
Two root causes for the waterfall/monitor lockup when scrolling past the
2.4 MHz RTL-SDR span:
1. safe_terminate() sent SIGKILL but never called wait(), leaving a
zombie process that kept the USB device handle open. The subsequent
capture restart failed the USB probe and the monitor could not use
the shared IQ path, falling back to a process-based monitor that
stole the SDR from the waterfall.
2. When the frontend created a new WebSocket after a failure, the old
handler's finally block called _set_shared_capture_state(running=False)
which could race with the new handler's running=True, making the
shared monitor path unavailable. Added a generation counter so only
the owning handler can clear the shared state.
When restarting capture for a new frequency, the USB handle from the
just-killed process may not be released by the kernel in time for the
rtl_test probe inside claim_sdr_device. Add retry logic (up to 4
attempts with 0.4s backoff) matching the pattern already used by the
audio start endpoint.
Also clean up stale shared-monitor state in the frontend error handler
so the monitor button is not left disabled when the capture restart
fails.
- _waitForPlayback now only succeeds on playing/timeupdate events, not
loadeddata/canplay which fire from just the WAV header before real
audio arrives
- stopMonitor() pauses audio and updates UI immediately instead of
blocking on the backend stop request (1+ second delay)
- Reduced backend audio stop sleep from 1.0s to 0.15s; the start
retry loop already handles USB contention

When dashboards (satellite, ADS-B, AIS) are loaded via iframe with
?embedded=true, the full navigation bar was still rendered, creating
a "UI in UI" effect. Pass the embedded query param from route handlers
to templates and conditionally skip the nav include.

- Persist ACARS/VDL2 messages across page refresh via new /acars/messages
and /vdl2/messages endpoints backed by FlightCorrelator
- Add clear buttons to ACARS/VDL2 sidebars and right-panel datalink section
with /acars/clear and /vdl2/clear endpoints
- Fix right-panel DATALINK MESSAGES flickering by diffing innerHTML before
updating, with opacity transition for smooth refreshes
- Add aircraft deselect toggle (click selected aircraft again to deselect)
- Enrich VDL2 messages with ACARS label translation (label_description,
message_type, parsed fields) matching existing ACARS translator

ACARS messages use IATA codes (e.g. UA2412) while ADS-B uses ICAO
callsigns (e.g. UAL2412). Add a translation layer so the two can
match, enabling click-to-highlight and datalink message correlation.

Add ACARS label translation, message classification, and field parsers
so decoded messages show human-readable descriptions instead of raw
label codes (H1, DF, _d, 5Z, etc.). Integrate translated ACARS
messages into the ADS-B aircraft detail panel and add a live message
feed to the standalone ACARS mode.
- New utils/acars_translator.py with ~50 label codes, type classifier,
and parsers for position reports, engine data, weather, and OOOI
- Enrich messages at ingest in routes/acars.py with translation fields
- Backfill translation in /adsb/aircraft/<icao>/messages endpoint
- ADS-B dashboard: DATALINK MESSAGES section in aircraft detail panel
with auto-refresh, color-coded type badges, and parsed field display
- Standalone ACARS mode: scrollable live message feed (max 30 cards)
- Fix default N. America ACARS frequencies to 131.550/130.025/129.125
- Unit tests covering all translator functions

The previous fix (bf8b308) introduced a regression: when VIS parity
check failed or the VIS code was unrecognized, the detector entered
DETECTED state permanently and never resumed scanning. Now it resets
to IDLE on validation failure and only enters DETECTED on success.
Also resets partial image progress counter between consecutive decodes
and adds SDR device claiming to general SSTV route to prevent conflicts.
