Refactor GatewayController to integrate GatewayCache

- Updated CMakeLists.txt to require gateway_cache component.
- Modified gateway_controller.hpp to include GatewayCache and adjust constructor.
- Removed internal scene and group management logic from GatewayController, delegating to GatewayCache.
- Simplified scene and group operations by utilizing GatewayCache methods for enabling, setting details, and deleting.
- Eliminated NVS storage handling code, as scene and group data is now managed by GatewayCache.
- Updated command handling methods to use cached data instead of internal structures.
