Add comprehensive Home Assistant schema validation tests

- Created detailed test suite for Home Assistant schema validation
- Implemented schemas for entities, services, events, configurations, automations, and device controls
- Added robust validation for complex Home Assistant data structures
- Enhanced type safety and validation for Home Assistant-related interfaces
- Expanded schema definitions to support multiple use cases and edge scenarios
