feat: add per-ride history charts with wait time and uptime tracking

Adds a cron-driven sampler that snapshots Queue-Times waits and Six Flags
Fast Lane data every 5 minutes into a new ride_wait_samples table, and a
clickable per-ride detail page at /park/[id]/ride/[slug] with Today / 7d /
30d Recharts views plus a 30d uptime pill. Rides are keyed by Queue-Times'
stable qt_ride_id so renames don't fragment history. Samples store
pre-bucketed local_date and local_time in the park's IANA timezone so
aggregations are pure SQL and DST-safe.
