### TL;DR
Added session cleanup logic to handle active organization reassignment when user organizations are deleted.
### What changed?
Enhanced the `cleanupUserOrganizations` method in `AuthService` to reassign active organizations for users whose current active organization is being deleted. The method now:
- Identifies users who are members of organizations being deleted
- Finds alternative organizations for each affected user
- Updates their sessions to use a fallback organization or null if no alternatives exist
- Wraps the entire operation in a database transaction for consistency
### How to test?
Run the new test suite:
```bash
bun test app/server/modules/auth/__tests__/auth.cleanup-user-organizations.test.ts
```
The test verifies that when a user's organization is deleted, other members' sessions are properly updated to use their remaining organization memberships as the active organization.
### Why make this change?
Prevents orphaned session references when organizations are deleted. Without this change, users could have sessions pointing to non-existent organizations as their active workspace, leading to potential application errors or inconsistent state.
