Replace the JSON f32 array (~7.5 KB/frame) with a named SSE event "b"
carrying base64-encoded i8 bins (~1.4 KB/frame, ~5x reduction):
event: b
data: {center_hz},{sample_rate},{base64_i8_bins}
1 dB per step covers the -128…+127 dBFS display range, sufficient for
visualization. RDS is stripped from the spectrum frame and emitted as a
separate named "event: rds" only when the payload changes. The JS
decoder uses atob() + sign-extension to reconstruct the float bin array.
A minimal inline base64 encoder is added server-side (no new crate).

- Add "Enable HF APRS" toggle button to the HF APRS tab (same style as
FT8/WSPR); button is disabled during TX like other decoder toggles
- app.js: sync button text/colour from SSE state updates
- hf-aprs.js: connect button click to /toggle_hf_aprs_decode
- bookmarks.js: add "HF APRS" checkbox to Add/Edit Bookmark decoder
section; bmReadDecoders/bmWriteDecoders handle "hf-aprs" key; bmApply
toggles the decoder to match bookmark preference on recall

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

Server emits an SSE sentinel event (history_done) after replaying
stored history. Client buffers all incoming messages until the sentinel
arrives, then drains the buffer in 30-event chunks via setTimeout so
the browser can handle input between batches. Live events after the
sentinel are dispatched immediately as before.

Add cwAutoLocalOverride flag in cw.js to block server-state snapshots
from overriding the checkbox while a user-initiated POST is in-flight.
Expose applyCwAutoUiFromServer for app.js render() to call instead of
applyCwAutoUi, preventing a racing SSE event carrying the old cw_auto
value from immediately undoing the user's toggle.

Fix CW picker redraw when the decoder sub-tab becomes visible to avoid
