Mirrors what aiolabs/withdraw did — hooks lnurlp's existing CRUD into
the LNbits nostr transport layer so an HTTP-allergic client (e.g.
lamassu-next ATM) can manage PayLinks over kind-21000 encrypted
events instead of HTTP.
Extends the existing `lnurlp_start()` lifecycle hook (auto-invoked
by the LNbits extension manager) to import the transport's
`register_rpc` and register five RPCs:
lnurlp_create AUTH_WALLET
lnurlp_get AUTH_WALLET
lnurlp_list AUTH_ACCOUNT
lnurlp_update AUTH_WALLET
lnurlp_delete AUTH_WALLET
All handlers are thin shims around the existing crud.py functions —
no business logic duplication. *_get / *_update / *_delete verify
that the link's stored wallet matches the caller's wallet id.
Also registers a link-owner resolver with the core subscriptions
module (tag "lnurlp", extras-key "link" — the default, matching
where views_lnurl.py:86 stamps the link id on settlement). That lets
clients call `subscribe_payments({tag:"lnurlp", link_id:...})` and
stream real-time pay events without polling, with ownership enforced
server-side.
The transport import is guarded by try/except ImportError so this
extension still loads cleanly against an LNbits build that doesn't
have nostr_transport.
