feat: use dateless Six Flags API endpoint for live today data

The API without a date param returns today's operating data directly,
invalidating the previous assumption that today's date was always missing.

- Add fetchToday(apiId, revalidate?) to sixflags.ts — calls the dateless
  endpoint with optional ISR cache
- Extract parseApiDay() helper shared by scrapeMonth and fetchToday
- Update upsertDay WHERE clause: >= date('now') so today can be updated
  (was > date('now'), which froze today after first write)
- scrape.ts: add a today-scrape pass after the monthly loop so each run
  always writes fresh today data to the DB
- app/page.tsx: fetch live today data for all parks (5-min ISR) and merge
  into the data map before computing open/closing/weatherDelay status
- app/park/[id]/page.tsx: prefer live today data from API for todayData
  so weather delays and hour changes surface within 5 minutes
- scrapeRidesForDay: update comment only — role unchanged (QT fallback)
