feat(events): public ticket page at /events/ticket/:ticketId

Target of the emailed ticket link the extension now builds under the
webapp root. Anonymous, like the LNbits UI's own /events/ticket/{id}:
reads the PublicTicket, resolves the event name (Nostr store → scoped
relay query → public REST as a last resort), and renders the logo QR
with paid / pending / checked-in state.
