Pull request overview

This PR adds two new API endpoints for managing individual contest task settings: one to retrieve task settings and another to edit them. The implementation includes service layer logic, repository changes to support both create and update operations, custom validation for date constraints, and the necessary route handlers.

Changes:

• Added GetContestTaskSettings and EditContestTask methods to the contest service for managing individual task settings within contests
• Renamed repository method from AddTaskToContest to SaveContestTask and changed from Create to Save to support both adding and updating contest tasks
• Added ContestTaskSettings schema and EndAtAfterStartAt struct-level validator to ensure EndAt is after StartAt
