JS: fix stereo AudioData channel copy — frame.copyTo with planeIndex:0
only fills the left plane; reading it as interleaved data caused every
other sample to be zero, making WFM stereo play at half speed. Now
calls copyTo per channel with the correct planeIndex.
Rust WFM: replace integer output_decim/output_counter in WfmStereoDecoder
with a fractional phase accumulator (output_phase_inc = audio_rate /
composite_rate). Integer division caused the effective output rate to
drift from audio_sample_rate when the SDR rate is not an exact multiple
(e.g. 2 MHz SDR → 250 kHz composite → ~50 kHz output instead of 48 kHz,
making audio play 4% slow).
Rust non-WFM: add resample_phase/resample_phase_inc to ChannelDsp and
use a fractional-phase resampler in process_block for non-WFM paths,
ensuring exactly audio_sample_rate samples/sec regardless of SDR rate.

Fix waterfall overview freezing at steady state by tracking a monotonic
push counter instead of row array length — the array size stays constant
once the waterfall is full, so the previous row-count comparison never
triggered the incremental draw path.
Fix WFM RDS not decoding when switching to WFM from a narrowband mode:
set_mode now resets audio_bandwidth_hz to the mode-appropriate default
(180 kHz for WFM) before rebuilding the FIR, preventing the 57 kHz RDS
subcarrier from being filtered out.
Add 1×/10×/100× multiplier button group next to the jog unit selector.
jogUnit × jogMult gives the effective jog step; both are persisted to
localStorage independently.

Poll GetSpectrum every 200 ms in remote_client via a dedicated timer that
bypasses the main state-watch channel (no SSE noise). The resulting
SpectrumData is stored in FrontendRuntimeContext::spectrum and served by
a new GET /spectrum endpoint (JSON or 204 when unavailable).
HTTP frontend shows a spectrum panel (canvas + frequency axis) only when
the rig reports filter_controls=true (i.e. SoapySDR). The canvas renders:
- dark background with dBFS grid lines
- green FFT spectrum line with semi-transparent fill
- red dashed vertical marker at the currently tuned frequency
- frequency axis labels (MHz/kHz) below the canvas

Three root causes prevented APRS decoding at 144.800 MHz with PKT/FM mode:
1. `RealIqSource::read_into` returned zeros — the SoapySDR streaming API
was never wired up. `RxStream<Complex<f32>>` is `Send` and
`StreamSample` is implemented for `num_complex::Complex<f32>` in the
soapysdr 0.3 crate, so the stream can read directly into the IQ buffer.
Now creates and activates an `RxStream` in `new()` and calls
`stream.read` in `read_into`.
2. PKT mode used `Passthrough` (take `.re`) demodulation. VHF/UHF packet
radio (APRS, AX.25) is FM-encoded AFSK — it must be FM-demodulated
before the APRS decoder sees the audio tones. Changed PKT to `Fm`.
3. `iq_read_loop` always slept `block_duration_ms` after each read. Real
hardware already blocks inside `read_into`; the extra sleep doubled
latency. Added `IqSource::is_blocking()` (default `false`; `true` for
`RealIqSource`) and skip the throttle sleep for blocking sources.

Replace the per-sample ring-buffer FIR convolution with block-level
overlap-save convolution using rustfft. For a block of M samples and
N taps the old approach costs O(N·M); the new one costs O(M log M),
with rustfft using SIMD (AVX2/SSE4) internally.
Key changes:
- Add rustfft = "6" dependency
- Add BlockFirFilter: overlap-save filter with pre-computed H(f) and
a single forward+inverse FFT pair per block (no per-sample multiply)
- ChannelDsp.process_block() now:
1. Batch-mixes entire block to baseband in one vectorisable loop
2. Applies BlockFirFilter to I and Q (one FFT pair each)
3. Decimates and demodulates as before
- Keep the old FirFilter for unit tests (sample-by-sample interface)
- Add BlockFirFilter unit tests (DC passthrough, length preservation)
- IQ_BLOCK_SIZE promoted to pub const for use in filter sizing
For the default config (4096-sample blocks, 64 taps, decim=40):
Old: ~262144 multiply-adds per FIR × 2 components = ~524k per block
New: ~2 × (3 × 8192 × log2(8192)) ops, all SIMD-vectorised by rustfft

When rigs are configured without explicit IDs in TOML, they now
receive auto-generated IDs based on model name and index (e.g.,
"ft817_0", "soapysdr_1"). Previously, the default empty ID prevented
auto-generation from triggering.
Changes:
- Set RigInstanceConfig default id to empty string (was "default")
- This allows resolved_rigs() auto-generation to trigger for all rigs
- Legacy single-rig path still gets explicit "default" ID
- Auto-generated IDs now appear in HTTP API /rigs endpoint
- Rig picker now displays auto-IDs correctly
The fix ensures that rigs without explicit ids get proper identifiers
that appear in the protocol and frontend selectors.
