Fix menu navigation issues with Bluetooth and initial focus

- Initialize menu context when showing menu to properly track focused item
- Fix double-activation bug that caused immediate exit from Bluetooth menu
- Add separate refresh_bt_device_list() to avoid infinite discovery loop
- Delete old BT page before creating new one to prevent memory leaks
- Add "Clear Paired" option to Bluetooth menu
- Improve Bluetooth menu refresh behavior to show "Scanning..." message
