The buyer-side webapp Purchase button needs allow_fiat to know
whether to surface the fiat method, and fiat_currency for the
conversion-preview label. Without these in the published Nostr
event, the buyer would either have to REST-fetch the LNbits event
again (defeats the inventory-sync goal) or guess.

Same backwards-compat reasoning as the four counter tags — tags
are AIO additions outside the NIP-52 spec; unknown tags are
ignored by spec-compliant clients.

- tickets_allow_fiat: "true" when the organizer enabled the fiat
  toggle. Omitted otherwise so the on-the-wire payload stays
  small for the common Lightning-only case.
- tickets_fiat_currency: only emitted when allow_fiat is on
  (otherwise it'd be ambiguous what the value represents).
