- Add unique constraint on participantSeasonResults(participantId, sportsSeasonId)
and rewrite upsert to use onConflictDoUpdate, eliminating race conditions and
sequential N*2 queries on sync
- Fetch pending mappings for all sport types; extend Unmatched card to show for
individual sports and route resolve-mapping to participantSeasonResults for
season_standings sports
- Replace hardcoded SEASON_STANDINGS_SIMULATOR_TYPES Set with
sportsSeason.scoringPattern === "season_standings" to avoid drift
- Remove countCompletedRaces() from F1 adapter — gamesPlayed/winPct were computed
but discarded by the orchestrator for season_standings sports
- Replace duplicate parseRacingStatsMap() with the shared statsMap() from espn.ts
