Fix Pay User lightning payment bugs

- Fix default amount showing fiat instead of sats when lightning payment selected
- Fix invoice response field name (bolt11 instead of payment_request)
- Fix NameError in payables/pay endpoint (wallet -> auth.user_id)
- Add get_user_wallet_settings_by_prefix() for truncated 8-char user IDs
- Update user-wallet endpoint to handle truncated IDs from Beancount accounts

+Centralized Authorization Module for Castle Extension.
+
+Provides consistent, secure authorization patterns across all endpoints.
+
+Key concepts:
+- AuthContext: Captures all authorization state for a request
+- Dependencies: FastAPI dependencies for endpoint protection
+- Permission checks: Consistent resource-level access control
+
+Usage:

+
+    @router.get("/api/v1/admin-endpoint")
+    async def admin_endpoint(auth: AuthContext = Depends(require_super_user)):
