WiP testing

[Yostra]

Summary

Add a local, OpenAPI-driven Stripe list server (@stripe/sync-test-utils) so tests no longer depend on the remote rate-limited Stripe API. The server runs in-process against Postgres, implements list/retrieve for every endpoint discovered from the spec, and supports auth guards and fault injection.

Building the test infrastructure uncovered bugs in the production code:

• List function sent unsupported params
• starting_after and limit were sent to every endpoint regardless of whether the spec advertises them (e.g. reporting_report_types)
• v2 created filters ignored
• the source hardcoded supportsCreatedFilter: false for all v2 endpoints even when the spec declares created.
• Sync errors silenced (service workflows marked pipelines as ready even when the sync had failed)

New tests:

test-server-all-api:
syncs every stream for every supported API version through the real engine

test-server-sync / test-sync-engine:
engine-level sync and state checkpoint tests with boundary tests and edge cases

test-e2e-network:
network disruption and fault injection: pauses Stripe/Postgres/Temporal containers mid-sync, injects auth failures and transient 500s, validates recovery and error propagation through the full service stack
