refactor: clean Docker files and restore standalone model services

- Remove all Docker-related files (Dockerfiles, compose.yaml)
- Remove documentation files (README, ARCHITECTURE, docs/)
- Remove old core/ directory (base_service, service_manager)
- Update models.yaml with correct service_script paths (models/*/server.py)
- Simplify vLLM requirements.txt to let vLLM manage dependencies
- Restore original standalone vLLM server (no base_service dependency)
- Remove obsolete vllm/, musicgen/, flux/ directories

Process-based architecture is now fully functional on RunPod.
