feat: P2.8 Resources/Equipment Booking (PostgreSQL + VNCdirectory)

- PostgreSQL schema: resources + resources_bookings tables with indexes
- Server-side client with PG pool + in-memory fallback for dev
- API routes: list, get, availability check, book, cancel
- Resource store (Zustand) for client-side state
- ResourcePicker component: type filter, search, availability dots
- Integrated into event-modal: auto-book on save, auto-cancel on delete
- Integrated into free-busy-view: resource availability rows
