Add date editing with conflict detection and rental booking editing

- BookingDetailPanel: edit dates/room with inline conflict detection; options to force-save or swap conflicting booking's room
- BookingsPage + CalendarPage: pass rooms/allBookings/onBulkUpdate to panel
- RentalBookingModal: accept editBooking prop to pre-populate fields for editing
- RentalPage: add edit (pencil) button per booking row, unify create/update handler
