Class customers can move a booking to another future session of the
same template from the manage page. Full target sessions place the
booking on the waitlist; freeing a confirmed seat drains the old
session's queue via the existing promotion path. Reminders re-arm
for the new time.

CustomerBookingView now carries tenantSlug/serviceId/staffId/
classSessionId so the manage page can query live availability; class
bookings resolve their session title as the display label. Reschedule
rejects waitlisted/completed bookings and session-bound class bookings
(400), collapsing a dead branch in the appointment path.
The manage page reschedule dialog replaces free-form date/time inputs
with a date → availability-slot picker filtered to appointment mode,
so customers can only move to a genuinely free slot with the correct
duration; 409 surfaces "slot just taken". Actions are status-gated:
reschedule for confirmed/pending appointments, cancel for live
bookings, explanatory note for class bookings.
