## Summary by CodeRabbit

* **Bug Fixes**
* Admin dashboard storage history now returns a continuous day-by-day
trend, carrying forward the last known workspace and blob storage values
for days without samples.
* Active member counts for workspace analytics were corrected to reflect
active workspace members.
* **New Features**
* Admin workspace member roles are now returned via a dedicated role
enum, serialized as enum name strings (e.g., `Owner`).
* **UI Improvements**
* Renamed key labels to “Active Members” and “Members and Invitations”;
member roles use pill badges and non-accepted statuses are shown.
* **Tests**
* Added E2E coverage for role enum serialization and strengthened
storage history assertions.
