fix(courts): use club detail courts data instead of separate fetch

Root cause: GET /admin/clubs/{id}/courts endpoint doesn't include
sport_variation nested structure, but GET /admin/clubs/{id} does.

Changes:
- Updated AdminClubDetail.courts to use Court[] type (includes sport_variation)
- ClubDetailTabs now passes courts + onUpdate callback to ClubCourtsTab
- ClubCourtsTab accepts courts as props instead of fetching separately
- Removed redundant getCourts() API call
- Removed debug logging

This fixes the court edit dropdown issue where sport variation wasn't
displaying because the data wasn't available from the courts endpoint.
