Add event_starts_at timestamp to scoring events for sub-day ordering (#146)
- New `event_starts_at timestamptz` column on `scoring_events`; backfilled
  from `event_date` (midnight UTC) via migration for all existing rows
- Admin create/edit forms consolidated from separate Date + Time inputs into
  a single `datetime-local` field; server derives `eventDate` from the UTC
  date portion of `eventStartsAt` so calendar-window queries continue to work
- Edit form pre-fill computed client-side via useEffect to avoid server-timezone
  mismatch for non-UTC admins
- Sort fix: replaced `eventDate ?? earliestGameTime.split("T")[0]` with
  `toEventSortKey` helper that prefers `earliestGameTime ?? eventDate` so
  bracket events with only per-game timestamps sort in the correct calendar position
- DB sort queries updated to use `eventStartsAt` as a tiebreaker after `eventDate`
- F1/IndyCar/golf events now populate `earliestGameTime` from `eventStartsAt`,
  giving time display in `UpcomingCalendarPanel`
- Bulk import gains optional `HH:MM` (UTC) third column
- New unit tests for `toEventSortKey` and `eventStartsAt` model behavior
