Three issues caused POCSAG messages to be incorrectly hidden or
misclassified in the Device Intelligence panel:
1. detectEncryption used a narrow character class ([a-zA-Z0-9\s.,!?-])
to measure "printable ratio". Messages containing common printable
ASCII characters like : = / + @ fell below the 0.8 threshold and
returned null ("Unknown") instead of false ("Plaintext"). Simplified
to check all printable ASCII (\x20-\x7E) which correctly classifies
base64, structured data, and punctuation-heavy content.
2. The default hideToneOnly filter was true, hiding all address-only
(Tone) pager messages. When RF conditions cause multimon-ng to decode
the address but not the message content, the resulting Tone card was
silently filtered. Changed default to false so users see all traffic
and can opt-in to filtering.
3. The multimon-ng output parser only recognized "Alpha" and "Numeric"
content type labels. Added a catch-all pattern to capture any
additional content type labels that future multimon-ng versions or
forks might emit, rather than dropping them to raw output.

The registry used plain int keys (device index), so HackRF at index 0
and RTL-SDR at index 0 would collide. Changed to composite string keys
("sdr_type:index") so each SDR type+index pair is tracked independently.
Updated all route callers, frontend device selectors, and session restore.

Tap the rtl_fm → multimon-ng audio pipeline via a relay thread to extract
RMS/peak amplitude levels and render a 60fps canvas oscilloscope during
pager decoding, giving visual feedback of RF activity before messages are
fully decoded.

Reverts IQ pipeline and removes syncWaterfallToFrequency calls from
pager, sensor, rtlamr, DMR, SSTV, and SSTV general modes. Waterfall
is now exclusive to listening post mode.

Replace rtl_fm/rtl_433 with rtl_sdr for raw IQ capture when available,
enabling a Python IQ processor to compute FFT for the waterfall while
simultaneously feeding decoded data to multimon-ng (pager) or rtl_433
(sensor). Falls back to the legacy pipeline when rtl_sdr is unavailable.

Stream threads for sensor, pager, acars, rtlamr, dmr, and dsc modes
never called release_sdr_device() when their SDR process crashed,
leaving devices permanently locked in the registry. Also fixes orphaned
companion processes (rtl_fm, rtl_tcp) not being killed on crash, start
path failures leaking processes, DMR stop handler missing lock, and
listening post/audio websocket pkill nuking all system-wide rtl_fm
processes. Wires up register_process()/unregister_process() so the
atexit/signal cleanup safety net actually works, and adds rtl_tcp,
rtl_power, rtlamr, ffmpeg to the killall endpoint.

Implements centralized tracking of SDR device allocation to prevent
multiple decoders from trying to use the same device simultaneously.
- Add sdr_device_registry with claim/release/status functions in app.py
- Update all SDR-based routes to claim devices on start and release on stop
- Return HTTP 409 with DEVICE_BUSY error when device is already in use
- Clear registry on /killall
- Skip device claims for remote connections (rtl_tcp, remote SBS)

Features:
- Add rtl_tcp support for pager and sensor decoding
- Connect to remote RTL-SDR via rtl_tcp server
- New UI toggle and host:port inputs in sidebar
- Supports rtl_fm and rtl_433 with remote devices
- Add remote dump1090 support for ADS-B tracking
- Connect to dump1090 SBS output on remote machine
- New "Remote" checkbox with host:port in ADS-B dashboard
Backend changes:
- Add rtl_tcp_host/port fields to SDRDevice dataclass
- Add is_network property for detecting remote devices
- Update RTLSDRCommandBuilder to use rtl_tcp:host:port format
- Add create_network_device() to SDRFactory
- Add validate_rtl_tcp_host/port validation functions
- Update pager, sensor, and adsb routes to accept remote params
Note: dump1090 doesn't support rtl_tcp directly - use remote
dump1090's SBS output (port 30003) for remote ADS-B tracking.
Security:
- Add input validation for all API endpoints (frequency, lat/lon, device, gain, ppm)
- Add HTML escaping utility to prevent XSS attacks
- Add path traversal protection for log file configuration
- Add proper HTTP status codes for error responses (400, 409, 503)
Performance:
- Reduce SSE keepalive overhead (30s interval instead of 1s)
- Add centralized SSE stream utility with optimized keepalive
- Add DataStore class for thread-safe data with automatic cleanup
New Features:
- Add data export endpoints (/export/aircraft, /export/wifi, /export/bluetooth)
- Support for both JSON and CSV export formats
- Add process cleanup on application exit (atexit handlers)
- Label Iridium module as demo mode with clear warnings
Code Quality:
- Create utils/validation.py for centralized input validation
- Create utils/sse.py for SSE stream utilities
- Create utils/cleanup.py for memory management
- Add safe_terminate() and register_process() for process management
- Improve error handling with proper logging throughout routes
