Add synchronous startup verification after Popen() — sleep 0.5s and poll
the process before returning to the caller. If SatDump exits immediately
(missing device, bad args), raise RuntimeError with the actual error
message instead of returning status: 'started'. Keep a shorter (2s) async
backup check for slower failures.
Also fix --source_id handling: omit the flag entirely when no serial number
is found instead of passing "0" which SatDump may reject. Change start()
and start_from_file() to return (bool, str|None) tuples so error messages
propagate through to the HTTP response.

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.

Security: replace path traversal-vulnerable str().startswith() with
is_relative_to(), anchor path checks to app root, strip filesystem
paths from error responses, add decoder-level path validation.
Architecture: use safe_terminate/register_process for subprocess
lifecycle, replace custom SSE generator with sse_stream(), use
centralized validate_* functions, remove unused app.py declarations.
Bugs: add thread-safe singleton locks, protect _images list across
threads, move blocking process.wait() to async daemon thread, fix
timezone handling for tz-aware datetimes, use full path for image
deduplication, guard TLE auto-refresh during tests, validate
scheduler parameters to avoid 500 errors.
Docker: pin SatDump to v1.2.2 and slowrx to ca6d7012, document
INTERCEPT_IMAGE fallback pattern.
