shadow's commonio_open() refuses to modify a user/group database whose
last line has no trailing newline, failing with a misleading
"cannot open /etc/passwd". Under 'set -e' this aborted the whole setup
at the fish step (and would later break docker's groupadd/usermod too).
- add ensure_db_trailing_newlines() to normalize /etc/passwd, /etc/group
and /etc/shadow before any user/group modification
- switch default shell via 'usermod -s' with a 'chsh' fallback, warning
instead of aborting the script on failure
Detect insufficient swap from RAM heuristics, suggest additional size,
and let the user create a persistent /swapfile during server setup.

Run visudo validation and sudoers.d checks with sudo so Debian no longer
fails with a false validation error. Prompt before installing Docker and
move AOSC Docker packages into the same optional install path.

Ubuntu 26.04+ ships Docker in its own repositories, so install
docker.io, docker-compose-v2, and docker-buildx directly from apt
instead of adding Docker's official repository. Falls back to the
official repo method for older Ubuntu versions.

Split curl download from bash execution so network errors are caught
explicitly. Add post-install verification that brew is actually
available before reporting success.
