Public Calendar: Finance Hearing Timeslots Not Shown

[calebyhan]

Motivation

Finance hearing dates are managed through a dedicated admin panel and stored as FinanceHearingDate records, separate from the CalendarEvent model. The public meetings/calendar page (/meetings) only fetches CalendarEvent records via GET /api/events. As a result, scheduled finance hearing timeslots never appear on the public-facing calendar, even when the hearing season is active.

Deliverables

• Either: surface finance hearing dates on the public calendar by fetching GET /api/finance-hearings alongside events on the meetings page and merging the results into the CalendarWidget
• Or: when a finance hearing date is created/updated in the admin panel, automatically create/sync a corresponding CalendarEvent (type "Finance Hearing") so it flows through the existing calendar pipeline
• Finance hearing slots marked as full (is_full = true) should be visually distinguishable on the calendar (e.g. greyed out or labeled "Full")

Important Notes

• The CalendarWidget accepts a CalendarEvent[] prop; the cleanest frontend-only approach is to transform FinanceHearingDate objects into synthetic CalendarEvent-shaped objects before passing them in
• If taking the backend sync approach, deleting a FinanceHearingDate should also remove the corresponding CalendarEvent
