feat: add PostgreSQL database integration for projects

- Add SQLx with Postgres support and migration system
- Create projects table with status enum and auto-updated timestamps
- Implement database queries and API response conversion layer
- Add Justfile commands for database management and seeding
- Integrate health checks for both Bun and database connectivity
