fix(cli): honest User-Agent tokens on jobbank and jobdanmark detail

jobbank sent a full Chrome browser string and jobdanmark's detail
command a bare Mozilla/5.0. Both now use the (compatible; <portal>-cli/1.0)
token per the identification posture settled in #277. Verified live:
both portals serve identical responses to the honest token.
