Refactor GatewayModbus and GatewayNetwork components

- Updated GatewayModbusConfig to allow uart_port and pin values to be -1, indicating an unconfigured state.
- Enhanced GatewayNetworkService to support an additional setup AP button with configurable GPIO and active low settings.
- Refactored boot button configuration logic to reduce redundancy and improve clarity.
- Introduced a new method for handling GPIO input configuration.
- Improved boot button task loop to handle both boot and setup AP buttons more effectively.
- Added programming mode functionality to EtsDeviceRuntime, allowing toggling and querying of the programming state.
- Implemented memory checks to avoid unnecessary reads in EtsDeviceRuntime.
- Enhanced security storage to derive factory FDSK from the device's serial number and store it in NVS.
- Updated factory FDSK loading logic to ensure proper key generation and storage.
