The decode canvas was always black because nothing drew on it. Now the
backend encodes partial JPEG snapshots every 5% progress and the frontend
uses an <img> tag with in-place DOM updates instead of recreating innerHTML
on every SSE event.

Shows the current VIS detection state machine position (Idle, Leader,
Break, Start bit, Data bits, etc.) in the signal monitor. This helps
diagnose why decoding may not be starting - e.g. if the VIS detector
is stuck in Idle despite a leader tone being present, the signal may
not contain a valid VIS header.

The Doppler tracking thread emits detecting events every 5s from a
separate thread, unaware of decode state. The previous to_dict() change
included signal_level for ALL detecting events, causing the frontend to
replace the decode progress canvas with the signal monitor mid-decode.
Fix: use None as default for signal_level so only signal-metrics events
(which explicitly set the value) include the field. Also add a frontend
guard to ignore detecting events while the UI is in decoding state.

The to_dict() method was skipping signal_level when it was 0, so the
frontend never received the field and never rendered the monitor.

When rtl_fm exits unexpectedly, read its stderr output to diagnose
the failure (no device, permission denied, etc.) and include the
error message in both the server log and the SSE progress event
sent to the browser.

Three bugs preventing the live SSTV pipeline from working:
1. Race condition: self._running was set AFTER starting the decode
thread, so the thread checked the flag, found it False, and exited
immediately without ever processing audio.
2. Ghost running state: when the decode thread exited (e.g. rtl_fm
died), self._running stayed True. The decoder reported as running
but was dead, and subsequent start() calls returned without doing
anything - permanently stuck until app restart.
3. VIS detection fragility: unclassifiable windows at tone transition
boundaries (mixed energy from two tones) caused the state machine
to reset from LEADER/BREAK states back to IDLE, dropping valid
VIS headers on real signals.

slowrx is a GTK GUI app that doesn't support CLI usage, so the SSTV
decoder was silently failing. This replaces it with a pure Python
implementation using numpy and Pillow that supports Robot36/72,
Martin1/2, Scottie1/2, and PD120/180 modes via VIS header auto-detection.
Key implementation details:
- Generalized Goertzel (DTFT) for exact-frequency tone detection
- Vectorized batch Goertzel for real-time pixel decoding performance
- Overlapping analysis windows for short-window frequency estimation
- VIS header detection state machine with parity validation
- Per-line sync re-synchronization for drift tolerance

rtl_fm stderr was sent to DEVNULL, hiding the actual failure reason
(rc=1). Now captured and surfaced in the error response. Also drains
rtl_fm stderr during normal operation to prevent pipe blocking.

Use -o - (stdout) instead of -o /dev/null for audio output, as
dsd-fme expects specific output targets. Remove -N flag which may
cause issues in headless mode. Add stderr capture on pipeline
failure for better error messages.

dsd-fme uses different protocol flags than classic dsd (e.g. -fs for
DMR instead of -fd, -f1 for P25 instead of -fp). Add -N flag to
disable ncurses terminal which is required when reading from stdin pipe.

- Fix SDRDevice attribute access (use getattr instead of dict .get())

The sweep loop's WiFi/BT/RF scan processing had unprotected
timeline_manager.add_observation() calls that could crash an entire
scan iteration, silently preventing all device events from reaching
the frontend. Additionally, scan interval timestamps were only updated
at the end of processing, causing tight retry loops on persistent errors.
- Wrap timeline observation calls in try/except for all three protocols
- Move last_*_scan timestamp updates immediately after scan completes
- Add per-device try/except so one bad device doesn't block others
- Emit sweep_progress after WiFi scan for real-time status visibility
- Log warning when WiFi scan returns 0 networks for easier diagnosis
- Add known_device and score_modifier fields to correlation engine
- Add TSCM scheduling, cases, known devices, and advanced WiFi indicators
