feat: Enhance MeshCoreBleService with new callbacks and message handling

- Added new callback types for path updates, message sent, message delivered, status responses, binary responses, and battery/storage information.
- Implemented handling for binary responses and path updates, including parsing and notifying via callbacks.
- Updated message sending logic to include acknowledgment and delivery confirmation.
- Enhanced log parsing for received data, including detailed interpretations and analysis.
- Introduced status request functionality to query operational status from repeater or sensor nodes.
- Updated battery and storage information handling to provide detailed metrics and trigger callbacks.
- Deprecated legacy methods in favor of more robust alternatives.
