Guest names (attendees)

With Guest names enabled, the classic checkout shows a Guests section with one field per seat in the cart. Names are saved as order meta _seatpass_attendees and copied onto the ticket.

• The buyer can edit the names later from My Account → Orders → View

  (the form is nonce-protected).

• The organizer can edit them in the Guest names box on the order screen.
• Edits re-sync the ticket, web page, email card and PDF (the PDF cache key

  includes the names, so a fresh PDF is produced).
