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.

Adds a phosphor-persistence waveform scope showing audio RMS/peak
levels during ISS SSTV and General SSTV decoding, matching the
existing pager scope pattern with a purple color scheme.

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.

SSTV was not claiming/releasing SDR devices through the centralized
registry, so the device state panel always showed the device as idle
during SSTV use. Added claim_sdr_device/release_sdr_device on the
backend and reserveDevice/releaseDevice on the frontend, matching the
pattern used by all other modes.

Users can now manage decoded SSTV images with download and delete actions
accessible from hover overlays on gallery cards, the full-size image modal
toolbar, and a "Clear All" button in the gallery header. Both ISS and
General SSTV modes are supported.

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.

Shows RMS audio level bar and SSTV tone classification (leader/sync/noise)
via SSE during detecting mode, replacing the static "Listening..." state
with actionable signal feedback.

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
