feat(phase-0): setup Docker Compose with TypeScript monorepo structure

- Create monorepo structure with apps/ and packages/
- Add Docker Compose for api, web, db, redis, worker services
- Migrate existing Express.js logic to TypeScript with 100% backward compatibility
- Preserve all existing API endpoints (/api/track, /api/v1/track) with identical behavior
- Setup development environment with hot reload and proper networking
- Add comprehensive TypeScript configuration with path mapping
- Include production-ready Dockerfiles with multi-stage builds
- Maintain existing rate limiting (100 req/hour/IP) and response formats
- Add health checks and graceful shutdown handling
- Setup Turbo for efficient monorepo builds and development
