Subject: feat(routes): add realtime estimates panel with pattern-aware styling

- New GET /api/stops/estimates endpoint (nano mode: tripId, patternId, estimate, delay only)
- useStopEstimates hook wiring estimates to routes-$id stop panel
- Pattern-aware styling: dim schedules and estimates from other patterns
- Past scheduled departures shown with strikethrough instead of hidden
- Persist selected pattern in URL hash (replace navigation, no history push)
- Fix planner arrivals using new estimates endpoint
