dsd-fme remapped several flags from classic DSD: -fp is ProVoice (not
P25), -fi is NXDN48 (not D-Star), -fv doesn't exist. This caused P25
to trigger ProVoice decoding and D-Star to trigger NXDN48. Corrected
flag table and added C4FM modulation hints for better sync reliability.
Also fixes: device panel showing "DMR" regardless of protocol, signal
activity status flip-flopping between LISTENING and IDLE, and rtl_fm
squelch chopping the bitstream mid-frame. Adds PPM correction and
relax CRC controls for fine-tuning on marginal signals.

When the backend has an active DMR session but the frontend lost track
(page refresh, broken flags causing silent running), clicking Start
returned 409 with no recovery path. Now the frontend resyncs on
"Already running" responses and checks backend status on tab activation.

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.

The dmrRawOutput div was rendering garbled box-drawing characters from
the dsd-fme ASCII art banner below the signal activity canvas. Remove
the div and filter banner lines (box-drawing chars, version info) in
the parser so they never become events.

The stream thread used a blocking readline() with no timeout, so once
DSD finished outputting its startup banner there were no more events
until actual signal activity. The frontend decayed to zero and appeared
dead. If DSD crashed, the synthesizer state never transitioned to
'stopped' so there was no visual or textual indication of failure.
- Use select() with 1s timeout on DSD stderr to avoid indefinite block
- Send heartbeat events every 3s while decoder is alive but idle
- Detect DSD crashes: capture exit code and remaining stderr, send as
'crashed' status with details and show notification to user
- Frontend properly transitions synthesizer to 'stopped' on process
death (was only happening on user-initiated stop)
- Increase idle breathing amplitude so LISTENING state is clearly
visible (0.12 +/- 0.06 vs old 0.05 +/- 0.035)
- Release device reservation on crash, not just user stop

DMR was missing checkDeviceAvailability/reserveDevice/releaseDevice
calls that other modes (SSTV, listening post) use, so the device
dropdown showed device 0 as available even when another process held
it. Also detect USB claim errors from rtl_fm and surface a clear
message telling the user to pick a different device.

The DSD stderr parser had regex ordering bugs that swallowed voice and
call events as bare slot events, and only matched classic dsd output
format (not dsd-fme). Unmatched lines were silently dropped, leaving
the signal activity panel with nothing to display.
- Reorder regex checks: TG/Src before voice before slot
- Support dsd-fme comma-separated format (TG: x, Src: y)
- Make bare slot regex strict (only standalone "Slot N" lines)
- Forward unmatched DSD lines as raw events for diagnostics
- Add LISTENING state to signal activity panel for raw output
- Show raw decoder output text below synthesizer canvas
- Fix test mocks for find_dsd() tuple return value

getBoundingClientRect on the canvas itself (sized via CSS width:100%)
instead of parentElement with arbitrary offset, preventing zero-width
canvas when flex layout timing varies.
