chore: Remove legacy Docker configuration and documentation

### Summary of Changes
- Deleted `docker-compose.dev.yml` and `docker-compose.yml` files to streamline the project structure.
- Removed outdated Dockerfiles for services (API Gateway, Service Adapters, API Docs, and Frontend) to eliminate redundancy.
- Updated `env.example` to reflect changes in service configurations, including local host settings for PostgreSQL and Redis.
- Revised `README.md` to remove references to Docker deployment and clarify local development setup instructions.
- Cleaned up documentation structure by removing obsolete files related to Docker rate limits and compatibility fixes.

### Expected Results
- Simplified project setup and improved clarity for developers by focusing on current configurations and removing legacy artifacts.
