feat: indie status page MVP -- FastAPI + SQLite

- 8 DB models (services, incidents, monitors, subscribers, etc.)
- Full CRUD API for services, incidents, monitors
- Public status page with live data
- Incident detail page with timeline
- API key authentication
- Uptime monitoring scheduler
- 13 tests passing
- TECHNICAL_DESIGN.md with full spec
