Fix frontend compilation warnings by removing dead code

- Remove unused Route enum and yew_router import from sidebar.rs
- Remove unused last_fetched field from ExternalCalendarEventsResponse
- Prefix unused variables with underscore (_preserve_rrule, _until_date, etc.)

Frontend now compiles cleanly with no warnings.
