feat: implement scheduled/recurring analysis with change alerting

Add APScheduler-based background task that periodically re-analyzes
tracked companies and alerts on significant patent count changes.

- Add tracked_companies and alerts tables to database schema
- Add SPARC/scheduler.py with configurable interval and threshold
- Add admin endpoints: GET/POST/DELETE /admin/tracked, GET /admin/alerts
- Scheduler starts at app startup; interval via SCHEDULE_INTERVAL_HOURS
- Change threshold configurable via CHANGE_THRESHOLD_PERCENT env var
- apscheduler is optional; graceful fallback if not installed

Closes leeworks-agents/SPARC#22
