- Add validation in create_game() and quick_create_game() to ensure both
teams are successfully fetched from SBA API before creating game
- Raise HTTP 400 with clear error message if team data cannot be fetched
- Add warning logs in get_teams_by_ids() when teams are missing from result
- Prevents games from being created with null team display info (names,
abbreviations, colors, thumbnails)
Root cause: get_teams_by_ids() silently returned empty dict on API failures,
and game creation endpoints didn't validate the result.
