## Summary by CodeRabbit

* **Bug Fixes**
* Fixed Stripe subscription syncing for Team plans to update the correct
existing local subscription (avoiding duplicates) while refreshing
quantity and billing/trial period details.
* **UI/UX Improvements**
* Improved workspace member list loading/error states with shared UI
components and steadier pagination behavior.
  * Refined fallback styling for cleaner, more stable layout.
* **Tests**
* Expanded subscription and projection coverage and adjusted
seat-allocation/e2e assertions to be more robust.
