feat(gateway): implement GatewayController and enhance GatewayRuntime

- Added GatewayController class to manage gateway operations, including command handling, scene and group management, and BLE state management.
- Introduced methods for scene and group storage, including loading, saving, and deleting scenes/groups.
- Enhanced GatewayRuntime with BLE management capabilities, including methods to check and set BLE state, and to generate BLE gateway names.
- Implemented utility functions for string normalization and CSV parsing.
- Added notification sinks for various events in the GatewayController.
