Feature: Update ESP Firmware OTA

[maitiSoutrik]

Add a new MCP tool update_firmware_ota(project_path: str, ip_address_or_hostname: str) for Over-The-Air firmware updates.

Functionality:

• Takes project_path (for the new firmware binary) and the device's IP address or hostname.
• Implements OTA update protocol (e.g., using espota.py or a custom HTTP OTA client if the firmware supports it).
• Reports update progress and success/failure status.
