Refactor AirStatus: transformar script em API WebSocket com FastAPI

[newthiagoassisk8]

This merge request converts the original AirStatus script, which previously ran via the terminal, into a WebSocket API using FastAPI.
It allows clients to connect and receive real-time updates on the AirPods battery status.

Key changes:

Implementation of a WebSocket server using FastAPI.

Continuous broadcasting of AirPods data to all connected clients.

Code modularization to improve maintainability and support future extensions.

Removal of terminal-based execution as the main script.

Motivation:

With this change, AirPods monitoring can now be integrated into web applications or more user-friendly interfaces, such as a React dashboard.
