feat: Add more top-level Stripe endpoints and unit tests

Adds support for the following top-level Stripe API resources:
- CustomerBalanceTransaction (incremental)
- ApplicationFee (incremental)
- SetupAttempt (incremental)
- CreditNote (incremental)
- ShippingRate (full refresh)
- Dispute (full refresh)
- SubscriptionItem (full refresh)
- CheckoutSession (full refresh)

These endpoints have been integrated into the existing Stripe analytics source,
configured for either incremental or full refresh data loading as appropriate.

Comprehensive unit tests have been added for these new endpoints and a
selection of pre-existing top-level endpoints to ensure correct behavior and
prevent regressions. The tests mock Stripe API calls and verify DLT resource
creation and data handling.

Note: Initial exploration and implementation for nested Stripe resources
were undertaken but subsequently reverted as per your request to focus
this effort solely on top-level resources. The Type C (conceptual)
endpoints from your list are covered by data within these
top-level resources.
