- Change fulfillment state from RESERVED to PROPOSED (Square rejects RESERVED)
- Return 503 from slots API when CalDAV is unreachable instead of serving empty
busy blocks that made all time slots appear falsely available
- Add BookingRequestPanel and /api/booking-request endpoint: when the calendar
server is down, customers can submit their order and preferred time; server
emails info@beachpartyballoons.com and sends a confirmation to the customer
