DEV: Restructure docker_manager deprecated routes

Update imports in `docker_manager` plugin to reflect new file structure,
moving files to nested directories for better organization. These changes
help improve code clarity and maintainability across controllers, models,
routes, and templates. No functional behavior changes introduced.
