Pull request overview
This PR adds scoreboard and proset (problem set) functionality for the Random-Set contest mode introduced in PR #197. The Random-Set mode assigns different problems to adjacent contestants to prevent cheating in exam scenarios.
Changes:
- Implemented random-set specific scoreboard with IOI 2013 scoring rules and first-kill tracking
- Added random-set proset page showing user-specific problem assignments
- Integrated scoreboard updates with the judge service
- Added access control checks to prevent users from viewing/submitting problems not in their assigned set

In this PR, we complete the peripheral features of the Random-Set PR, including the scoreboard and proset.
Currently, the random set scoreboard only supports the IOI 2013 rule, which also appears to be the only rule used by schools.
Since integration tests cannot simulate clients with different IP addresses, the related tests are deferred to the E2E stage.
