Convert nextion to message bus

Pull request overview

This PR migrates Nextion display interactions from direct NextionControl “external update” calls to a centralized MessageBus publish/subscribe model, so UI pages react to system events rather than being pushed update payload structs.

Changes:

• Inject MessageBus* through NextionFactory, BasePage, and various Nextion pages; pages now subscribe to bus events instead of overriding handleExternalUpdate().
• Update command handlers (SensorCommandHandler, AckCommandHandler, BaseNextionCommandHandler) to publish state changes onto the MessageBus.
• Extend MessageBus with additional event types for UI/system metrics and sensor updates.
