## Summary by CodeRabbit

* **Refactor**
* Consolidated subscription visibility and “active” selection logic so
all subscription queries use a shared, consistent filter across the
platform.

* **Tests**
* Added a test to ensure expired subscriptions are excluded from active
subscription results.
* Updated test fixtures to differentiate expired, unexpired, and onetime
subscriptions for more accurate coverage.
