fix import

Both interfaces had identical structures, so unified them into a single
CalendarEventSubscriptionData interface that is used for both REST API
responses and WebSocket subscription data.

Changes:
- Removed CalendarEventRestData interface
- Updated fetchCalendarEvents to use CalendarEventSubscriptionData
- Added documentation clarifying the interface is used for both APIs
