Migrate all platforms to abstract base classes

[puddly]

We've already migrated the larger platforms, this migrates the rest. I've also removed **kwargs from the async_ method calls for stronger typing.

This is just a code quality improvement and should have no external effects.

Pull request overview

This PR completes the migration of all platform entities to use abstract base classes (ABC), improving code structure and type safety across the ZHA application. The changes remove **kwargs from async method signatures in favor of explicitly typed parameters, making the API more self-documenting and enabling stronger type checking.

Changes:

• Introduced abstract base classes for all remaining platform entity types (update, switch, siren, sensor, select, number, lock, light, fan, device_tracker, cover, climate, button, binary_sensor, alarm_control_panel)
• Removed **kwargs from async methods and replaced with explicitly typed parameters
• Moved common properties and methods to base classes while making entity-specific implementations abstract
