PM-5370 campus leaderboard

[vas3a]

This pull request makes two main improvements to the campus leaderboard report for Topcoder: (1) it adds a new field to indicate whether each submission has been reviewed, and (2) it simplifies access controls so that any authenticated user can read campus program leaderboards, including private groups. The changes include updates to SQL queries, TypeScript service logic, DTOs, and tests to support these features.

Campus leaderboard review status enhancements:

• Added a new reviewed field to the leaderboard report, which indicates whether a submission has been reviewed (as opposed to simply passing or failing review). This is reflected in the SQL (campus-leaderboard.sql), service types, and DTOs, and is covered by new and updated tests. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Access control simplification:

• Removed the requirement for group membership or special report access to view private campus group leaderboards; now, any authenticated user can access them. This involved removing related logic from the SQL (campus-leaderboard-group.sql), the service, and the controller, as well as updating tests to reflect the new behavior.

Test and code cleanup:

• Removed unused imports and parameters related to the old access control logic, and updated tests to match the new API and expected behaviors. [1] [2] [3]

DTO formatting improvements:

• Reformatted DTO imports for readability in leaderboard-generic.dto.ts and leaderboard-mm.dto.ts. [1] [2]
