fix(gro-609): include stripePaymentIntentId in invoice list and wrap stats endpoint in try/catch

- Add stripePaymentIntentId to the GET /invoices list query so the refund button
  renders when seed data includes a payment intent ID
- Wrap /api/invoices/stats/summary in try/catch so errors return 200 with zero
  defaults instead of 5xx, preventing the Invoices page from crashing on
  mount for groomer-role sessions
