Refactor RF Configuration Management (#2245)

- Introduced RFConfiguration class to encapsulate RF settings and operations.
- Replaced direct usage of RFConfig structure with iRFConfig instance across multiple files.
- Updated frequency handling in actuatorSomfy, gatewayPilight, gatewayRF, and gatewayRF2 to use iRFConfig.
- Modified webUI to interact with iRFConfig for RF settings management.
- Removed deprecated RFConfig structure and related functions.
- Enhanced JSON handling for RF configuration loading and saving.
- Improved logging for RF configuration operations.
