[feat](trx-rs): add HF APRS decoder (300 baud, 1600/1800 Hz AFSK)

Browse Source 
Adds a second APRS demodulator path tuned for the HF APRS standard
(300 baud Bell 103-style AFSK, mark=1600 Hz / space=1800 Hz), active
on RigMode::DIG.  Shares AX.25 framing, APRS parsing, APRS-IS uplink,
and frontend display with the existing VHF stack.

- trx-aprs: parameterise Demodulator::new(); add AprsDecoder::new_hf()
- trx-core: HfAprs variant in DecodedMessage; hf_aprs_decode_enabled /
  hf_aprs_decode_reset_seq in RigState/RigSnapshot; SetHfAprsDecodeEnabled
  and ResetHfAprsDecoder commands; handlers.rs fallback arm updated
- trx-protocol: client command variants + bidirectional mapping; test
  fixture updated
- trx-server: run_hf_aprs_decoder() task (activates on DIG mode);
  hf_aprs history in DecoderHistories; rig_task command dispatch;
  aprsfi uplink forwards HfAprs via OR-pattern
- trx-frontend: hf_aprs_history in FrontendRuntimeContext
- trx-frontend-http: prune/record/snapshot/clear helpers; SSE history
  replay; toggle_hf_aprs_decode + clear_hf_aprs_decode endpoints;
  /hf-aprs.js endpoint; HF APRS tab in web UI
