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.
