fix: merge upstream PR sanjoyg#196 — ikea_bulb_device_set registration fix

Cherry-pick from sanjoyg#196 (by pablotoledo).

Two fixes:
1. ikea_bulb_device_set now registers with registry_entry wrapper
   instead of directly, fixing AttributeError in sync_all_device_areas()
2. Use Python built-in ConnectionError instead of requests import
   for ConfigEntryNotReady handling
