Register kind-21000 RPC handlers on the core nostr_transport dispatcher so
the booking flow runs over relays with no HTTP, mirroring lnurlp:
- operator (AUTH_WALLET): room create/update/publish, block create — all
ownership-checked; room_list_mine (AUTH_ACCOUNT).
- public (AUTH_NONE): room_list/get (wallet id stripped), availability,
booking_request, booking_get. Guest identity is the signed sender_pubkey,
so no guest_pubkey is trusted from the body.
- register_link_owner_resolver(tag=chatelet, key=booking_id) lets the
operator stream settlements via subscribe_payments.
Handlers delegate to services.py — no logic duplicated. Graceful no-op if
the core transport module isn't in this LNbits build (pre-#4). Guests can't
subscribe to the operator wallet, so they poll booking_get to confirm.
Note documented in event-flow.md: with availability now an RPC, the custom
kind:22000/22001 pair is redundant for RPC clients (revisit in #2).
