- Wrap updateLeague call in try-catch so DB errors return a user-friendly
message instead of an unhandled 500
- Fix season-update catch block to say "season settings" not "league" since
the league was already saved successfully at that point
- Validate leagueId URL param against season.leagueId in draft board loader
to prevent accessing a season via the wrong league's URL
- Change 403 message for authenticated non-members from "not public" to
"you don't have access" to accurately reflect their logged-in state
- Add settings-update.test.ts covering name validation, league save,
error handling, draft speed mapping, and season-specific validation
- Add draft-board-access.test.ts covering public/private access rules,
leagueId mismatch detection, commissioner/owner/unauthenticated cases,
and the new per-role 403 message distinction
