Subject: [PATCH] feat(events): guest checkout in the purchase dialog with
 delivery email

Buyers no longer need an account to buy a paid ticket. The dialog gains a
"Your details" block (name for guests, email + confirm-email for everyone,
prefilled from the account email) as a vee-validate/zod form, and builds
its rail buttons from the event's published payment methods so an
organizer can run card-only events.

- Fiat: same-tab redirect to the provider right after the POST, with the
  pending checkout (ticket ids, email) remembered in localStorage for the
  return page; the two-step "open in new tab" panel is gone.
- Lightning: guests get the bolt11 QR + "Open in wallet" and settle via
  the existing poll; the LNbits-wallet button stays login-only.
- Free tickets remain login-gated (events#29).
- Guest success state renders the ticket QRs inline with the "emailed
  to" note, since guests have no My Tickets.

i18n keys added under events.purchase / checkout / ticket (en, es, fr).
