Fix remove-analyst silent failure caused by set -e + pipefail

The script was exiting silently on the GROUPS=$(groups ... | cut ...)
line — set -eo pipefail caused bash to terminate the script before any
echo output, making it appear to do nothing.

Replace set -euo pipefail with set -u and explicit error handling.
Admin scripts must always report what happened, never exit silently.

Also: use id -nG instead of groups|cut pipe, add verification step
after userdel, and log each operation for visibility.
