- 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.

Number(null) evaluates to 0 which passes Number.isFinite(),
causing aprsHasValidCoordinates(null, null) to return true.
This made initAprsMap() center the map at [0,0] (Gulf of Guinea)
at zoom 8 instead of the US default, hiding all station markers
off-screen.
Add null guards (lat != null && lon != null) to reject null/undefined
while still accepting 0 as a valid equator coordinate.

Add flex-shrink: 0 to .section, .run-btn, and .stop-btn so flex
children maintain natural height and the sidebar scrolls instead
of compressing content on 1080p displays.

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.

Timer threads now log on fire and catch all exceptions so scheduled
captures never die silently. Frontend connects SSE when the scheduler
is enabled (not only on manual Start) and polls /wefax/status every 10s
as a fallback so the UI stays in sync with auto-fired captures.

Replace window.open() with a fullscreen modal matching the SSTV
pattern: toolbar with download/delete SVG buttons, close button,
click-outside-to-close, and confirmation before delete.

stop() was returning before the decode thread could save any partial
image to disk, so the frontend loadImages() call found nothing new.
Join the decode thread (2s timeout) before returning — with select()-
based reads the thread exits within ~0.5s so this stays responsive.

- Replace blocking stdout.read() with select()-based non-blocking reads
so the decode thread responds to stop within 0.5s
- Make stop() non-blocking by releasing the lock before terminating the
process and removing the redundant wait()
- Move initial scanning SSE event from start() into the decode thread so
it fires after the frontend EventSource connects
- Update frontend stop() to give immediate UI feedback before the fetch

rtl_fm subprocess failures (missing tool, no SDR hardware) were silent —
add tool-path check and post-spawn health check in _start_pipeline(),
show errors prominently in the strip status bar (red text + red dot),
and include error detail in scheduler skip events.

Flash the Start button itself with amber pulse when clicked without a
station selected, and show "Select Station" in the strip status text
right next to the button so the error is immediately visible.
Add a 24-hour timeline bar with broadcast window markers, red UTC time
cursor, and countdown boxes (HRS/MIN/SEC) that tick down to the next
broadcast. Broadcasts show as amber blocks on the timeline track with
imminent/active visual states matching the weather satellite pattern.

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.
