SSE EventSource connections for AIS, ACARS, VDL2, and radiosonde were
not closed when switching modes, causing fd exhaustion after repeated
switches. Also fixes socket leaks on exception paths in AIS/ADS-B
stream parsers, closes subprocess pipes in safe_terminate/cleanup, and
caches skyfield timescale at module level to avoid per-request fd churn.
Closes#169

METEOR-M2-4 was defined as an active weather satellite but had no
orbital data, so pass predictions always returned empty. Added TLE

sqlite3.connect() opens read-only files without error — the failure

Extends the rtl_tcp support (added in c1339b6 for APRS, Morse, DSC) to
the weather satellite mode. When a remote SDR host is provided, SatDump
uses --source rtltcp instead of --source rtlsdr, local device claiming
is skipped, and the frontend sends rtl_tcp params via getRemoteSDRConfig().
Closes#166

When stopping gunicorn with Ctrl+C, the gevent worker's handle_quit()
calls sys.exit(0) inside a greenlet, causing gevent to print a
SystemExit traceback. Add a gunicorn config with post_worker_init hook
that marks SystemExit as a non-error in gevent's hub.

Closes#164. Only pager and sensor routes supported rtl_tcp connections.
Now aprs, morse, and dsc routes follow the same pattern: extract
rtl_tcp_host/port from the request, skip local device claiming for
remote connections, and use SDRFactory.create_network_device(). DSC also
refactored from manual rtl_fm command building to use SDRFactory's
builder abstraction. Frontend wired up for all three modes.

Blueprint registration and database init run synchronously (essential
for routing). Process cleanup, database cleanup scheduling, and TLE
satellite updates are deferred to a background thread with a 1-second
delay so the gevent worker can start serving HTTP requests right away.
Previously all init ran synchronously during module import, blocking
the single gevent worker for minutes while TLE data was fetched from
CelesTrak.
Also removes duplicate TLE update — init_tle_auto_refresh() already
schedules its own background fetch.

The custom SIGINT/SIGTERM handler in utils/process.py overrode
gunicorn's own signal management, causing KeyboardInterrupt to fire

has already installed handlers and defers to it.

Blueprint registration, database init, cleanup, and websocket setup
were all inside main() which only runs via 'python intercept.py'.
When gunicorn imports app:app, it got a bare Flask app with no routes,
causing every endpoint to return 404.
Extracted initialization into _init_app() called at module level with
a guard to prevent double-init when main() is also used.

Rate limiting on login is a security requirement, not optional.

Gunicorn's gevent worker (-k gevent) handles monkey-patching internally.

Mode modules were leaking EventSource connections, setInterval timers,
and setTimeout timers on every mode switch, causing progressive browser
sluggishness. Added destroy() to 8 modules missing it (meshtastic,
bluetooth, wifi, bt_locate, sstv, sstv-general, websdr, spy-stations)
and centralized all destroy calls in switchMode() via a moduleDestroyMap
that cleanly tears down only the previous mode.

Re-implements envelope detection on top of the rewritten Morse decoder.
Addresses PR #160 review feedback:
- Rebase: rebuilt on current upstream/main (lifecycle state machine)
- Gap thresholds: 2.0/5.0 for envelope only; goertzel keeps 2.6/6.0
- Frequency validation: max_mhz=1766 for envelope, 30 for goertzel
- Tests: EnvelopeDetector unit tests + envelope-mode decoder test
- Envelope uses direct magnitude threshold (no SNR/noise ref)
- Goertzel path completely unchanged

rtl_test opens the USB device during probing. After killing the
process, the kernel may not release the USB interface immediately.
dump1090 then fails with usb_claim_interface error -6. Add a 0.5s
delay after probe cleanup to allow the kernel to fully release the
device before the actual decoder opens it.

rtl_test -t often exits non-zero after finding a device (e.g.
"No E4000 tuner found, aborting" with R820T tuners). The return
code fallback was firing even when the "Found N device(s)" success
message had already been matched. Track device_found separately
and only use return code as fallback when no success was seen.

The success check ('Found' in line and 'device' in line) matched

The subprocess was launched with bare 'python' which on Debian doesn't
