feat(api): implement GET /api/zones/:id/history occupancy history endpoint

- Add hourly zone history snapshot recording that runs every hour
- Returns [{timestamp, count, people:[]}] in hourly buckets
- Supports period query parameter: 24h (default), 7d, 30d
- Zone history is persisted in zone_history SQLite table
- Initial snapshot recorded on startup for the current hour
