Add print log functionality and device name handling

- Introduced functions to capture and manage incoming print logs.
- Added a download link for the incoming print log in the web interface.
- Updated device name prefix for BLE and added device name building logic.
- Enhanced SerialCommand class with line handler support.
- Implemented WiFi reconnect logic and status tracking.
