Julian Pawlowski 98512672ae feat(lifecycle): implement HA entity best practices for state management 
Implemented comprehensive entity lifecycle patterns following Home Assistant
best practices for proper state management and history tracking.
Changes:
- entity.py: Added available property to base class
  - Returns False when coordinator has no data or last_update_success=False
  - Prevents entities from showing stale data during errors
  - Auth failures trigger reauth flow via ConfigEntryAuthFailed

- sensor/core.py: Added state restore and background task handling
  - Changed inheritance: SensorEntity → RestoreSensor
  - Restore native_value from SensorExtraStoredData in async_added_to_hass()
  - Chart sensors restore response data from attributes
  - Converted blocking service calls to background tasks using hass.async_create_task()
  - Eliminates 194ms setup warning by making async_added_to_hass non-blocking

- binary_sensor/core.py: Added state restore and force_update
  - Changed inheritance: BinarySensorEntity → RestoreEntity + BinarySensorEntity
  - Restore is_on state in async_added_to_hass()
  - Added available property override for connection sensor (always True)
  - Added force_update property for connection sensor to track all state changes
  - Other binary sensors use base available logic

- AGENTS.md: Documented entity lifecycle patterns in Common Pitfalls
  - Added "Entity Lifecycle & State Management" section
  - Documents available, state restore, and force_update patterns
  - Explains why each pattern matters for proper HA integration

Impact: Entities no longer show stale data during errors, history has no gaps
after HA restart, connection state changes are properly tracked, and config
entry setup completes in <200ms (under HA threshold).

All patterns verified against HA developer documentation:
