+Nostr-transport RPC handlers for the withdraw (LNURL-withdraw) extension.

+Names mirror the Lightning.Pub `withdraw.*` contract that the lamassu-next
+ATM consumes (see ~/dev/shocknet/lamassu-next/packages/lightning/src/client.ts
+lines ~301–351). That keeps the lamassu-next-side adapter a pure name
+translation — no semantic reshaping.
+
+Auth model (set in `__init__.py:withdraw_start`):
+- create / get / update / delete  → AUTH_WALLET; the calling pubkey must
+  own the wallet the link is scoped to. *_get / *_update / *_delete also
+  verify the link's stored `wallet` matches the caller's wallet id.
+
+`resolve_withdraw_owner` is registered with the core subscription module
+under tag `"withdraw"` and extras-key `"withdrawal_link_id"` (matching
+where the extension stamps the link id on settlement — see
+`views_lnurl.py:144`). That lets `subscribe_payments({tag:"withdraw",
