feat: Implement First Version

    This commit introduces the core functionality for discovering, pairing, connecting with and controlling the ESP32 "Remote Switch" device. 1. BLE scanning 2. device bonding 3. help page 4. BLE connecting 5. on/off control

    - Add BleScanManager to handle BLE scanning logic, filtering by the device name "Remote Switch".
    - Implement runtime permission requests for Bluetooth and Location (ACCESS_FINE_LOCATION, BLUETOOTH_SCAN, BLUETOOTH_CONNECT) to comply with Android 10.0+ requirements.
    - Add a BroadcastReceiver to listen for bond state changes and update the UI accordingly upon successful pairing.
    - Utilize SharedPreferences to persist the MAC address of the bonded device, allowing the app to remember the device across sessions.
    - Implement a "Reset" feature to unbond the device via reflection and clear the saved address from SharedPreferences.
    - Create a help page to list some instructions and give an access to navigate to the permission settings.
    - Add BleConnectManager to handle BLE connecting and command control logic, including time sync and servo control.
