Pull request overview

This PR updates the Android Auto/Automotive screens to stop using per-screen “friendly name/state” helpers and instead consume the resolved EntityDisplayItem stream from GetEntitiesForDisplayUseCase.observe(...), centralizing display metadata and live updates.

Changes:

• Replace Entity/friendlyName/friendlyState usage in vehicle screens with EntityDisplayItem + EntityDisplayState flows.
• Rework HaCarAppService and vehicle screens to observe entity display state (loading/loaded/error) rather than manually merging entity updates.
• Replace Entity.onPressed(...) with a parameterized onEntityPressed(entityId, currentState, ...) helper.

• The log message still refers to onPressed, but this screen now calls onEntityPressed(...). Updating the message (and ideally including the entityId) will make logs easier to understand.
