Cancel the caller's sign-up for an occurrence

Self-service de-registration. Flips the caller's live participation to `cancelled` (history is kept; a re-registration inserts a fresh row). The spot is locked once attendance is marked: a guarded update only flips rows still in `registered`, so an `attended`/`no_show` participation returns 409. Unknown occurrence or not signed up is 404.

DELETE/occurrences/{occurrence_id}/registration

Sign the caller up for an occurrence POST

Self-service registration (activity registration feature). The caller must hold a confirmed (paid or free) ticket in the occurrence's edition, and the activity's access rules apply: `staff_only` programs require an event staff role, and `min_access_level` gates on the ticket's access level. Inside a transaction the occurrence row is locked, occupancy is checked against `max_capacity`, and a duplicate active registration is rejected (409) — the partial unique index (`uniq_program_participations_active_per_occurrence_attendee`) is the concurrency backstop. Registering is always a fresh row: the participation ledger is append-only, cancelled rows free the slot.

List an occurrence's participants GET

The staff attendance surface: every live participation with the attendee's name/email from their registration. Any event staff (owner/admin/staff) may read it. Cancelled rows are history and are never listed — staff mark the people who are coming.
