fix(docker): pre-create runtime directories (#607)

- Added creation of runtime directories (`/container/user` and `/container/logs`) in the
  Dockerfile.
- Ensures these directories are created with appropriate permissions during image build.
- Prevents Docker from auto-creating these directories with root ownership at runtime,
  avoiding access issues.
