feat(applicant): My Logistics shows assigned hotel + room

Replace the program-level hotel.findUnique (broken after removing @unique)
with the caller's HotelStay (include hotel) on their AttendingMember.
Returns hotel: {name,address,link,notes}|null and room: {roomNumber,
checkInAt,checkOutAt}|null. MyLogisticsCard renders the Room section
(number + Monaco-time check-in/out) when room is present.
