feat: Implement command queue for BLE command handling
- Added BleCommandQueue to manage command serialization and responses in BleCommandSender. - Updated writeData, writeDataAndWaitForAck, and writeDataAndWaitForResponse methods to utilize the command queue. - Enhanced BleResponseHandler to complete commands based on responses received from the BLE device. - Introduced new commands for channel management, including getChannel and setChannel. - Created LocationTrailLayer and TrailControls widgets for displaying and managing location trails on the map. - Added PermissionRequestDialog to handle location permission requests on app startup. - Updated LocationTrackingService to allow GPS tracking without a BLE connection.
