fix(meshcore): BLE scan feedback and cancel-during-connecting

Browse Source 
- Scan button shows 'Scanning...' and disables during fetch; shows
  'No devices found' or 'Scan failed' on empty/error result; auto-
  selects device if only one is returned
- Disconnect button now enabled during 'connecting' state so users
  can cancel a stuck connection and retry with a different device
