decoder.reset() now finalises and saves any partially-received image
before returning to Idle. The server emits the completion event so the

Add signal-level detection that monitors luminance variance to auto-start
receiving when tuning in mid-image (~3s of sustained modulated signal),
matching fldigi's "strong image signal" detection. Reduce APT sustain
to 1.0s (2 windows) matching fldigi. Emit initial "Idle — scanning"
state event so the frontend shows the decoder is processing audio.
Add tracing instrumentation for luminance stats and tone analysis.

APT start/stop signals are not audio-frequency tones — they are
black↔white transition rates in the FM-demodulated output (300, 675,
450 transitions/s). The Goertzel detector was running on the raw ~1900 Hz
carrier where no energy exists at those frequencies, so APT detection
never fired on real HF WEFAX signals.
Replace the Goertzel approach with transition-counting on demodulated
luminance (matching fldigi's decode_apt), and swap the processing order
so FM demodulation runs before APT detection.

Two issues prevented bookmark decoder toggles from working:
1. bmPrefillFromStatus() did not prefill decoder checkboxes from the
current toggle button state, so bookmarks were saved with an empty
decoders array even when decoders were active.
2. The bookmark apply code fetched /status without the remote parameter,
comparing against the wrong rig's decoder state in multi-rig setups.

When tuning into a WEFAX station after the APT start tone has already
passed, the decoder stayed in Idle forever. Add an idle_phasing detector
that continuously runs phasing detection on demodulated luminance while
in Idle state, allowing the decoder to lock onto ongoing transmissions
without requiring the 300/675 Hz start tone.

All decoder toggle endpoints (APRS, HF-APRS, CW, FT8, FT4, FT2, WSPR,
LRPT, WEFAX) read the enabled flag from the global default state watch
instead of the target rig's state. When controlling a non-active rig the
toggle reads the wrong rig's flag and sends the wrong enable/disable
value, causing the button to have no effect or invert the state.
Add resolve_rig_state() helper that looks up the per-rig watch via
context.rig_state_rx() and falls back to the global default, matching
the pattern already used by the /status endpoint.

BackgroundDecodeManager.send_audio_cmd used the global active_rig_id()
to route virtual channel commands. During a rig switch, Remove commands
for the old rig's channels were sent to the new rig's audio pipeline,
leaving orphaned virtual channels on the previous rig's server.
Replace send_audio_cmd with send_audio_cmd_to_rig that takes an explicit
rig_id, derived from the channel's own rig_id field. Both Remove and
SubscribeBackground commands now reach the correct rig.

The lazy plugin loader (25c5940) deferred scheduler.js to the 'settings'
tab, but initSettingsUI() runs at app boot before the user clicks any tab.
This meant initScheduler was undefined at boot, so the scheduler-control-row
on the main tab never showed and status polling never started.
Two fixes:
1. Add 'settings' to the eagerly-loaded plugin list so scheduler.js and
vchan.js load at startup alongside digital-modes and bookmarks.
2. Add auto-init at the end of scheduler.js: if authRole is already set
when the script executes (late/lazy load), it self-initializes without
waiting for initSettingsUI(). This makes it resilient to any load order.

The lazy plugin loader introduced in 25c5940 incorrectly mapped

Settings → Scheduler, so the plugin must load with the 'settings' tab.

The #sat-status element was stuck on "Waiting for satellite pass" because:
1. The client audio handler (audio_client.rs) did not include AUDIO_MSG_LRPT_IMAGE
in its message type match, so LRPT image messages from the server were silently
dropped and never reached the frontend.
2. No progress was reported during active LRPT decoding — the only status update
happened when a complete image was finalized, which could take the entire pass.
3. The sat-status text was never updated when the decoder was enabled/disabled,
leaving it permanently at the HTML default text.
Changes:
- Add DecodedMessage::LrptProgress variant for live MCU progress reporting
- Send LRPT progress updates from the decoder task when new MCUs are decoded
- Add AUDIO_MSG_LRPT_IMAGE and AUDIO_MSG_LRPT_PROGRESS to client audio handler
- Update sat-status text when decoder state changes (enabled/disabled)
- Handle lrpt_progress messages in the frontend to show "Receiving — N MCU rows"
