feat: enhance entrypoint and Dockerfiles for flexible volume and permission management (#260)

* feat: enhance entrypoint and Dockerfiles for flexible volume and permission management\n\n- Support batch mount and permission fix in entrypoint.sh\n- Add coreutils/shadow (alpine) and coreutils/passwd (ubuntu) for UID/GID/ownership\n- Use ENTRYPOINT for unified startup\n- Make local dev and prod Dockerfile behavior consistent\n- Improve security and user experience\n\nBREAKING CHANGE: entrypoint.sh and Dockerfile now require additional packages for permission management, and support batch volume mount via RUSTFS_VOLUMES.

* chore: update Dockerfile comments to English only

* fix(entrypoint): improve local/remote volume detection and permission logic in entrypoint.sh

* Update entrypoint.sh
