APISignupsIdPublish

Publish a signup

Transitions status from `draft` to `published`. Idempotent — publishing an already-published signup is a no-op. Closed signups can't be republished (returns 409).

Cancel a registration DELETE

Removes a single participant row. Use this for organizer-driven cleanup (e.g. removing a duplicate or no-show). Participant-driven cancellation flows still go through the confirmation-token URL.

Send manual reminders to participants POST

Triggers an immediate reminder send. Skips participants who've already received one for this event. SMS-based today (email reminders ship via the day-before cron). Subject to the org's SMS ceiling.
