Create a free RSVP order

Creates a free RSVP order against a session and issues its tickets. Every line's ticket type must be free or comp; capacity is enforced atomically (concurrent claims for the last seat serialize — exactly one wins). Paid checkout is a separate flow.

Create a paid order + checkout link POST

Get an order GET

Returns a single order with its issued tickets.
