REORG/MINOR: mworker/cli: extract shared worker row printer for "show proc"

Introduce cli_append_worker_row() to centralize formatting of a single worker row.
Replace duplicated row-printing code in both current and old workers loops with the helper.
Motivation: Reduces LOC and improves readability by removing duplication.
