The junction table was a redundant second source of truth: syncTournamentResults
already fans out by querying scoring_events.tournamentId directly, so the table
only served the admin UI and could drift out of sync (causing orphaned events).
- Drop sports_season_tournaments table and all link/unlink admin actions
- Add getTournamentsBySportsSeason / getSportsSeasonsByTournament helpers that
derive the same information from scoring_events.tournamentId
- Add "Add Existing Tournament" dropdown to the events admin page (qualifying_points
seasons only) — selecting a tournament creates the scoring event in one step
- Fix clone: scoring events now carry tournamentId, fixing a latent check-constraint
violation when cloning qualifying_points seasons
- Tournament admin page "Linked Sports Seasons" is now a read-only derived view
