## Summary
- Adds `useHasMounted` hook (using `useSyncExternalStore` — no extra render cycle) to gate UTC timestamp formatting to client-only
- Fixes the visible time-flip in `EventSchedule` and `UpcomingCalendarPanel` where SSR rendered UTC time (e.g. "9:00 PM") and the client re-rendered with local time (e.g. "2:00 PM PDT") after hydration, with `suppressHydrationWarning` silently hiding the mismatch
- Fixes `formatEventDate` in `date-utils.ts` (and `EventSchedule`'s private copy) to parse `YYYY-MM-DD` strings as local midnight instead of UTC midnight, correcting an off-by-one day bug for UTC-negative users across all callers
## Test plan
- [ ] Navigate to a sports season page — confirm event times show in local timezone with no flash/flip on load
- [ ] Hard-reload the page — confirm no brief UTC time visible before settling on local time
- [ ] Check the home page `UpcomingCalendarPanel` — confirm same behavior
- [ ] Verify dates display correctly (e.g. no "Jun 17" showing for a "Jun 18" event near midnight UTC)

## Summary
- **Group stage match list**: Removed MD 1/2/3 headings; matches now listed chronologically under date separators (e.g. "Jun 14"). Kick-off time appears below the team names instead of between them.
- **Sort order**: \`findMatchesByGroupIds\` / \`findMatchesByEventId\` now order by \`scheduledAt ASC NULLS LAST\` so unscheduled matches always trail scheduled ones.
- **Groups/Bracket toggle**: When both group stage and knockout bracket exist, a toggle appears (mirroring the NBA/AFL standings toggle). Sports with both regular-season standings and a group stage get all views available.
- **Upcoming events**: \`getUpcomingEventsForDraftedParticipants\` now also queries \`groupStageMatches\`, so World Cup group fixtures appear on the home page calendar sorted by kick-off time with a label like "Group A — France vs Germany".
- **\`isAllCompete\` fix**: \`UpcomingEventsCard\` and \`UpcomingCalendarPanel\` now treat \`group_stage_match\` as a bracket-style event, showing team badges instead of "N of your picks".
Fixes#53
## Test plan
- [ ] Navigate to a World Cup sports season page — groups should be listed chronologically under date headers with no MD labels; kick-off time should appear below each match row
- [ ] Once the knockout bracket has matches, confirm the Groups/Bracket toggle appears and both views render correctly
- [ ] On the home page, a user with drafted World Cup participants should see upcoming group fixtures in the calendar panel with individual team badges (not a participant count)
- [ ] NBA/AFL/NHL pages unaffected — their standings/playoffs/finished toggle still works normally
- [ ] \`npm run typecheck\` and \`npm run test:run\` pass

- Fix UTC midnight rollover bug: server now queries from yesterday UTC
as a buffer; UpcomingCalendarPanel filters to local-today client-side
via useEffect + Intl.DateTimeFormat, removing the need for any
cookie or server-side timezone detection
- Cap homepage and league page panels at 6 events with a "View all" link
- Add /upcoming-events page (60-day view across all leagues)
- Add /leagues/:leagueId/upcoming-events page (60-day per-league view)
- Add emptyMessage prop to UpcomingCalendarPanel for context-specific copy
- Change getUpcomingEventsForDraftedParticipants to accept pre-computed
date strings instead of Date objects
