fix(bluetooth): auto-reconnect to paired devices after reboot

- Auto-set enableOnBoot=true when BT is enabled or device is paired,
  so board restarts with BT on and can reconnect
- Make RADIO_STATE_ON handler non-exclusive: scan for HID Host,
  start HID Device, SPP and MIDI all independently (was else-if)
- Improve HID Host auto-connect for RPA: direct addr match, name-match
  fallback, and direct connect to stored identity using resolving list
- Persist addrType in PairedDevice file for more reliable reconnection
- Add verbose logging for loadAll/save to debug missing files

Fixes issue where board restart did not reconnect to previously
connected BT devices. Also preserves f94cc160 fullscreen flag feature.
