Pierre Warnier 8ee65a7552 phase3: implement groupadd, groupdel, groupmod, grpck, chfn, chsh, newgrp ...

All 14 shadow-utils tools are now implemented.

groupadd: create groups with auto GID allocation, system groups, force mode.
groupdel: delete groups, checks for primary group usage.
groupmod: modify GID, rename, password changes.
grpck: verify /etc/group and /etc/gshadow integrity.
chfn: change GECOS sub-fields (name, room, phone).
chsh: change login shell with /etc/shells validation.
newgrp: change effective group with crypt(3) password verification.

449 tests, zero clippy warnings, all 14 tools in multicall binary.
