Subject: [PATCH] fix(tournament): improve birth year eligibility checks in
 TournamentTab

- Updated the logic for determining minimum and maximum birth years to support both camelCase and snake_case formats from the API.
- Enhanced member eligibility checks to ensure accurate filtering based on birth year restrictions, improving clarity and functionality in the tournament participant selection process.
