feat: enhance MQTT integration checks in JackeryHome

- Added validation to ensure MQTT integration is configured before setting up the JackeryHome integration.
- Updated error handling in the configuration flow to provide user feedback if MQTT is not available.
- Improved logging for MQTT subscription processes and error handling in the data coordinator.
- Updated user interface strings to reflect the new requirements for MQTT integration.
