giles 78d8fd54c5 cinema tickets: capacity-enforced buy across events→shop→identity (4 domains) ...

People can now buy tickets, from the web UI, with capacity enforcement — the heart of the model.

- Showing page (events): a 🎟 Tickets section (host/blog--showing-extras) shows capacity/sold + a Buy
  form per Offering (ticket type + price). host/blog--showing-capacity = the showing's override else
  its calendar's screen's default (via on-calendar → has-calendar reverse).
- host/blog-buy-ticket (events): CAPACITY-CHECKED (sold < capacity), then POSTs to shop /ticket and
  records showing --sold--> ticket. Sold out → the Buy form is replaced by 'sold out'.
- host/blog-ticket (shop): issues a Ticket (is-a ticket, for showing, bought-as offering, owned-by
  the person's email) + registers the person on the identity peer.
- host/blog-person (identity): find-or-create a Person keyed by email (login-optional) → person:<id>.
- IDENTITY is a new 4th fed-sx peer (sx_identity, SX_DOMAIN=identity, id.rose-ash.com-ready); shop
  gets SX_IDENTITY_BASE. serve.sh gains shop 'ticket' type + identity 'person' type seeds.

LIVE end-to-end: events.rose-ash.com/<showing> → Buy adult (alice@example.com) → sold 0→1, a ticket
on market.rose-ash.com, a person on identity. blog 218/218.
