fix: wire package/visitor events, bbox payloads, reel/timelapse scheduling

- Add `requests` to pyproject.toml dependencies (used by detection/weather.py)
- Wire PACKAGE_DELIVERED/REMINDER/COLLECTED and KNOWN/UNKNOWN_VISITOR event
  types in EventProcessor._classify_event
- Add normalized bbox to all detection payloads in camera worker
  (domestic_animal, wildlife, person, vehicle)
- Integrate highlight reel and timelapse scheduling in HealthMonitor.run()
