refactor(proxy): move proxy logic to services.mitmproxy and update Docker service model

- Rename DockerService to DockerContainer and add folder attribute
- Move proxy-related modules (models, validator) to services.mitmproxy
- Update imports and references to new module locations
- Refactor Docker utilities to use DockerContainer and improve service discovery
- Add manager.py with create_proxy utility stub
- Initialize discovered Docker services at app startup and warn if none found
