When a scheduler-managed decoder is manually disabled from the frontend,
take scheduler control first so the manual change overrides the current
scheduler cycle like a direct frequency change does.
Track decoder enabled state on the toggle buttons and only take over
when the click is actually disabling FT8, FT4, FT2, WSPR, or HF APRS.

Invalidate main-decoder windows whenever the rig's main frequency
changes, including direct SetFreq, scheduler-driven retunes, and
external CAT retunes observed during polling.
The decoder loops now resubscribe their PCM receivers on reset and drop
results that finish after the reset sequence advances, preventing false
decodes from stale pre-retune audio.

The WSPR 7-bit power field contains the raw dBm value (0-60) with no
offset. The decoder was subtracting 64, turning valid power values into
negative numbers that always failed the range check, causing
unpack_message to return None for every real signal. Also fix callsign
trimming to strip leading spaces from space-padded callsigns.

The deinterleave function had its indices swapped: it wrote
out[j] = symbols[p] instead of out[p] = symbols[j]. This fed
completely scrambled data to the Fano decoder, making convergence
impossible. Matched against the reference implementation in
raptor/lib/wsprd/wsprd_utils.c which does tmp[p] = sym[j].

The OSD-lite decoder was the source of FT2 false positives. It tries
685 CRC-14 checks across 5 passes (1 + 16 + 120 per pass), giving a
~4% chance of accepting random noise as a valid decode.
The reference implementation (decode174_91) verifies OSD results
against the received signal; the trx-rs OSD-lite only checked CRC.
Add ft2_count_hard_errors_vs_llr() which counts how many of the 174
coded bits in an OSD candidate disagree with the received hard
decisions. A legitimate correction disagrees in very few positions;
a false CRC match on noise disagrees in ~40-50 parity positions.
Reject OSD results with more than 36 hard errors.

The WSPR decoder was producing almost no valid decodes despite audible
signals. Three root causes:
- No sync vector: the 162-bit WSPR sync pattern was not used, so signal
detection relied on raw peak power which is unreliable.
- Coarse frequency search: 4 Hz steps with 1.465 Hz tone spacing could
miss signals entirely. Now uses 2 Hz coarse + 0.25 Hz fine refinement.
- Fixed timing: assumed signal starts exactly 1s into the slot. Now
searches +/-2s in 0.5s steps to handle real-world timing jitter.
Also evaluates up to 8 frequency/timing candidates per slot and reports
the actual measured timing offset in dt_s.

The previous SNR formula (cand->score * 0.5 - 29.0) used the adjacent
tone bin as a noise reference. On a crowded FT8 band that bin is often
occupied by another station, inflating the apparent noise floor by
10-15 dB and capping reported SNR at around -10 dB even for strong
signals.
Replace with ftx_post_decode_snr(): re-encode the decoded message to
obtain the exact per-symbol tone sequence, compare each signal bin
against the minimum of the remaining (noise-only) bins, average over
all valid symbols, and apply the WSJT-X 2500 Hz bandwidth correction
dynamically per protocol. This produces accurate SNR estimates for both
FT8 and FT4 regardless of band occupancy.

Add NEON (aarch64) vectorized paths mirroring the existing AVX2 paths:
- demod/math_arm.rs: replace the no-op placeholder with a full NEON FM
discriminator that processes 4 samples per iteration using a 7th-order
minimax atan polynomial and branchless atan2 with argument reduction,
matching the accuracy of the AVX2 path (max error ~2.4e-7 rad).
32-bit ARM retains the scalar fallback.
- dsp/filter.rs: add mul_freq_domain_neon() that deinterleaves 4 complex
pairs via vuzpq/vzipq, performs complex multiply with vmulq/vaddq/vsubq,
then reinterleaves. On aarch64 this path is always taken (NEON is
mandatory); scalar fallback remains for other targets.
