Phase 2.1: Backend project initialized with Docker configuration

- Created Cargo.toml with all required dependencies
- Implemented health/ready endpoints
- Added Docker configuration (production + development)
- Configured docker-compose with resource limits
- Set up MongoDB service with persistence
- Verified build (cargo check passed)
- Prepared monorepo structure for mobile/web/shared

Next: Phase 2.2 (MongoDB connection and models)
