feat: Add Fichero D11s thermal label printer support with REST API and CLI

- Implemented a new module for the Fichero D11s thermal label printer, including BLE and Classic Bluetooth interfaces.
- Created a REST API using FastAPI to manage printer status, info, and printing tasks (text and images).
