It called log_info/log_warn/error_exit/list_install_disks without
sourcing anything - leftover from before modules were run as
standalone subprocesses via run_module() rather than sourced into
installer.sh. Never noticed because the pipeline never reached this
module in a live run until now. Behavior unchanged: still just lists
disks and warns that partitioning is disabled (Phase 1).
