sjg cededd9c3f [fix](trx-rs): align FT2 downsample path with reference
Reuse a shared FT2 downsample FFT context per decode window and\nfix filter shift/bin handling to match the reference implementation.\n\nCo-authored-by: OpenAI Codex <codex@openai.com>

sjg d547c45a9c [feat](trx-rs): add FT2 decoder support (wired to FT4)
Mirrors the FT4 implementation across the full stack. The trx-ft8
crate wires Ft8Decoder::new_ft2() to FTX_PROTOCOL_FT4 as a
placeholder pending a dedicated FT2 implementation.

Changes:
- trx-ft8: Ft8Decoder::new_ft2() delegates to with_protocol(Ft4)
- trx-core: DecodedMessage::Ft2, AUDIO_MSG_FT2_DECODE (0x15),
  ft2_decode_enabled/ft2_decode_reset_seq state, SetFt2DecodeEnabled/
  ResetFt2Decoder commands, protocol mapping
- trx-server: DecoderHistories::ft2, run_ft2_decoder (7.5s slots),
  run_background_ft2_decoder, history push/replay, decoder task spawn
- trx-frontend-http: ft2_history in FrontendRuntimeContext,
  toggle/clear endpoints, /ft2.js route, bookmark/scheduler/background
  decode support, DecodeHistoryPayload ft2 field
- web: ft2.js plugin (3.75s period timer), FT2 subtab in index.html,
  FT2 map source (distinct hue), app.js dispatch, decode-history-worker
  HISTORY_GROUP_KEYS, bookmarks read/write/apply

  locators get their own distinct marker colour and filter chip

sjg b9744ef8fd [feat](trx-frontend-http): color radio paths by band or mode
Radio paths and decode contact paths now use the same color as the
marker they belong to, respecting the active filter mode:
- Band mode: color follows the band (golden-angle HSL hue)
- Mode/source mode: color follows the source type (FT8/WSPR/bookmark)

APRS, AIS, and VDES paths use their fixed source colors unchanged.
Decode contact paths sync color when the filter mode is switched.

CSS stroke/stroke-opacity removed from path classes so Leaflet's
color option takes effect; dasharray and flow animation are retained.

sjg a3c098b68f [fix](trx-ft8): correct FT8 SNR to WSJT-X 2500 Hz convention
The score from ft8_lib is an averaged uint8 difference between Costas
sync tones and their neighbours (each unit = 0.5 dB). The previous
score * 0.5 gave the signal-above-adjacent-noise in dB relative to a
single 3.125 Hz waterfall bin, yielding values of +5 to +50 dB —
all wrong.

Subtract 10*log10(2500/3.125) ≈ 29 dB to normalise to the 2500 Hz
reference bandwidth used by WSJT-X and expected by PSKReporter:

  snr = score * 0.5 - 29.0

This maps score 10 (minimum decodable) → -24 dB and score 60 → +1 dB,
matching typical WSJT-X SNR report ranges.
