Docker: Fix non-root execution issues. Remove 'set -eu' from user-setup.bash since it's sourced via BASH_ENV and affects all subsequent scripts. Use safe parameter expansion in jupyter-start.bash. Configure nsight service to start as root but switch to HOST_UID via USER environment variable. Add USER to common-service environment block for all containers.
