Add comprehensive unit and e2e tests for invoice collection, queue logic, and modal interactions:

- Introduced e2e test for "Change Invoice Collection" in `change-invoice-collection.spec.ts`.
- Added unit tests for `CollectedOrderInvoiceOverview.vue` including edit flow for `closed_at`.
- Implemented tests for queue reliability, state handling, and customer actions:
  - `CollectedOrderInvoicesQueueHistory.vue`: polling, error handling, richer diagnostics, and retry logic.
  - `InvoicingBillingPeriod` views: refresh and queue state handling.
- Enhanced test coverage for Stripe queue functionality and related actions.
