Code review fixes: earliestGameTime fallback, isNaN guard, and missing index

- getUpcomingScoringEvents: fall back to eventStartsAt.toISOString() when no
  game-level scheduledAt exists, matching the same pattern already used in
  getUpcomingEventsForDraftedParticipants — prevents F1/golf events from
  showing a date with no time in SportSeasonCard and similar consumers
- EventSchedule: replace bare toLocaleTimeString call with an isNaN-guarded
  block so a malformed timestamp renders nothing instead of "Invalid Date"
- database/schema.ts: add index on tournament_groups(scoring_event_id) to
  support the inArray filter added in the previous commit
  (run npm run db:generate && npm run db:migrate to apply)
