Fix 5 critical issues: provisioning storage, webhook auth, password exposure, middleware, model conflict

- Store VirtFusion provisioning info in credentials column instead of non-existent provisioning_info key
- Add PayPal webhook header verification to reject unsigned requests
- Stop exposing VPS root password in flash message, use separate new_password key
- Apply ensure_not_suspended middleware to account routes
- Rename User::invoices() to billingInvoices() to avoid overriding Cashier's invoices() method
