Fix multiple mode:restart state machine bugs in Motion Light

- Fix brightness threshold falsely resetting state to NONE during light
  transition ramp-up (brightness temporarily below threshold != light off)
- Fix false manual override from Zigbee attribute-only updates (on→on)
  by requiring meaningful state change (on→off or off→on)
- Fix disable guard to also accept ENABLING state (not just ENABLED)
- Move state updates before service calls to survive mode:restart cancellation
- Add ENABLING sub-case handler for motion-cleared-during-enable scenario
- Add CASE 1 default handler for restart recovery disable path
- Add comprehensive debug logging at automation entry and CASE 1 entry
- Change default timeout_delay to 0 and grace_period to 2s
- Remove unused is_debug/is_base_debug variables
