Fix: not rendering declined requests on google calendar

[interfinityOfficial]

Summary of Changes

DECLINED events were being hidden on the calendar because DECLINED was in CALENDAR_HIDE_STATUS. It was removed from that list in components/src/policy.ts so DECLINED events show on the calendar and are included in overlap checks, avoiding double bookings.
