[feat](trx-frontend-http): persist settings and APRS state across refresh

Browse Source 
Add localStorage persistence (trx_ prefix) for UI settings:
- Jog step, RX/TX volume (app.js)
- CW WPM, tone, threshold, auto-detect flags (cw.js)
- APRS decoded packets and running state (aprs.js)

APRS decoder auto-restarts on page refresh if it was active,
and all decoded packets plus map markers are restored from storage.
