feat: POST /tickets/{event_id}/{payment_hash} polling endpoint

Browse source 
The webapp's useTicketPurchase polls this every 2s after firing
Pay with Wallet (or after presenting the QR) to confirm payment
before advancing to the ticket-QR success state. Without this
endpoint the post-payment poll loop returns 404 indefinitely and
the buyer never sees their ticket land — even though set_ticket_paid
fired on the invoice listener and the row is correctly marked paid
in the DB.

Returns {paid: bool, ticket_id?: str}. A missing or cross-event
ticket returns paid: false rather than 404 so the poll loop doesn't
need to special-case the not-yet-created race.

The WebSocket at /tickets/ws/{payment_hash} is more efficient for
push notifications — this POST is the fallback for clients that
can't open a relay-side socket.
