1.4.3-beta.1

Summary

• Fix hub entity names not following integration translations (calendar + master switch)
• Calendar: remove hardcoded English name, use translation_key with has_entity_name=True
• Master switch: use entity translation (Calendar events / Événements calendrier) instead of device name only

Test plan

• Set HA server language to English → hub shows Shared calendar and Calendar events
• Set HA server language to French → hub shows Calendrier partagé and Événements calendrier
• Reload Expiration integration after upgrade (existing hub entities may need name restore in entity registry)
