feat: register transport RPCs over LNbits nostr transport

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.

+                    LNURL is a range of lightning-network standards that allow

+                    link that wallets use to fetch an invoice from a server
+                    on-demand. The link or QR code is fixed, but each time it is
+                    read by a compatible wallet a new QR code is issued by the
+                    service. It can be used to activate machines without them
+                    having to maintain an electronic screen to generate and show
+                    invoices locally, or to sell any predefined good or service
+                    automatically.

+                    <b>WARNING: LNURL must be used over https or TOR</b><br />
+                    LNURL is a range of lightning-network standards that allow
+                    us to use lightning-network differently. An LNURL-pay is a
+                    link that wallets use to fetch an invoice from a server
+                    on-demand. The link or QR code is fixed, but each time it is
+                    read by a compatible wallet a new QR code is issued by the
+                    service. It can be used to activate machines without them
+                    having to maintain an electronic screen to generate and show
+                    invoices locally, or to sell any predefined good or service
+                    automatically.
+                  </p>
+                  <p>
+                    Exploring LNURL and finding use cases, is really helping
+                    inform lightning protocol development, rather than the
+                    protocol dictating how lightning-network should be engaged
+                    with.

-      <p>
-        <b>WARNING: LNURL must be used over https or TOR</b><br />
-        LNURL is a range of lightning-network standards that allow us to use
-        lightning-network differently. An LNURL-pay is a link that wallets use
-        to fetch an invoice from a server on-demand. The link or QR code is
-        fixed, but each time it is read by a compatible wallet a new QR code is
-        issued by the service. It can be used to activate machines without them
-        having to maintain an electronic screen to generate and show invoices
-        locally, or to sell any predefined good or service automatically.
-      </p>
-      <p>
-        Exploring LNURL and finding use cases, is really helping inform
-        lightning protocol development, rather than the protocol dictating how
-        lightning-network should be engaged with.

+"""
+Nostr-transport RPC handlers for the lnurlp (LNURL-pay) extension.
+
+Exposes the same CRUD surface that `views_api.py` exposes via HTTP, but
+encrypted over kind-21000 events through the LNbits nostr transport.
+Mirrors the withdraw extension's `transport_rpcs.py`; both extensions
+hang their handlers off the core dispatcher via their `*_start()` hook.
+
+Auth model (set by the registrations in `__init__.py:lnurlp_start`):
+- *_create / *_get / *_update / *_delete → AUTH_WALLET. The transport
+  resolves the caller's pubkey to a wallet (admin access) before
+  invoking the handler, so we know `auth.wallet.id` and `auth.wallet.user`.
+- *_list → AUTH_ACCOUNT. The caller may list links across all wallets
+  they own, optionally narrowed by `request.wallet_id`.
+
+Ownership: *_get / *_update / *_delete also verify the link's stored
+`wallet` field matches the caller's wallet id — defense in depth, since
+a malicious client could otherwise probe link metadata they don't own.
+
+`resolve_lnurlp_owner` is registered with the core subscription module
+under tag `"lnurlp"` (default link_extra_key `"link"` — that's 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.
