CFG_DOCKER_MANAGER_USER / installDockerManagerUser was a chrooted SFTP file-access
user — unrelated to the LibrePortal control-plane manager (sudo_user_name), and
the source of the 'two managers' confusion. It was permanently-off dead code: the
gate CFG_DOCKER_MANAGER_ENABLED and the CFG_DOCKER_MANAGER_USER/_PASS keys are
defined in no config template, so it never ran. Its SSH-key-management sibling
(unused/ssh_manager.sh) was already retired; admin host SSH access is handled by
the current /ssh page + scripts/ssh/host_access.sh.
Move install_user_manager.sh / uninstall_user_manager.sh / check_manager.sh to
scripts/unused/manager/ (recoverable, matches the graveyard convention — not
deleted, in case the SFTP-user idea is rebuilt cleanly later), drop the two call
sites (start_preinstall.sh, check_requirements.sh), regenerate the arrays.
