When the user's wallet (e.g. Zeus) is connected to the same LND node
that LP uses, LNURL-withdraw fails because LND rejects the payment
with "no self-payments allowed". This is safe because LP always
decrements the user's balance before paying and refunds on failure.

When userPubkey is provided, resolve the ApplicationUser and call
applicationManager.PayAppUserInvoice instead of paymentManager.PayInvoice
directly. This ensures notifyAppUserPayment fires, sending
LiveUserOperation events via Nostr for real-time balance updates.

Store the Nostr pubkey of the user who creates a withdraw link so the
LNURL callback debits the correct user's balance instead of the app
owner's. Pass userPubkey through from RPC handler to WithdrawManager.
- Add creator_pubkey column (migration v4)
- Store creatorPubkey on link creation
- Pass creator_pubkey to payInvoice on LNURL callback

Initialize extension system before nostrMiddleware so registered
RPC methods are available. Extension methods (e.g. withdraw.createLink)
are intercepted and routed to the extension loader before falling
through to the standard nostrTransport.

Add POST /api/v1/withdraw/create endpoint to allow external apps (ATM,
web clients) to create LNURL-withdraw links via HTTP instead of RPC.
Changes:
- Add handleCreateWithdrawLink HTTP handler
- Fix route ordering: callback routes before wildcard :unique_hash
- Extract app_id from Authorization header (Bearer app_<id>)
- Use is_unique=false for simple single-use ATM links

Enable CORS on the extension HTTP server to allow cross-origin requests
from ATM apps and other web-based clients.

- Add extension loader initialization to startup
- Create mainHandlerAdapter to bridge mainHandler with extension context
- Mount extension HTTP routes on separate port (main port + 1)
- Configure EXTENSION_SERVICE_URL for LNURL link generation
