fix(auth): enforce dashboard authorization and improve team deletion

Add authorization gates to Project and Server creation buttons in the dashboard to prevent non-admin users from accessing resource creation. Improve team deletion to clear cache before deletion and automatically switch to the user's next available team.

- Hide create buttons from non-admin users in dashboard
- Clear cache before team deletion to prevent stale session resolution
- Switch user session to next available team when current team is deleted
- Handle refreshSession when user has no remaining teams
- Add tests for dashboard authorization enforcement and team deletion flow
