fix(#646): translate the Pin tab names row and list it in the Settings reference

The new App Settings row had no zh-CN entry, so it read in English in a
Chinese UI, and docs/wiki/Settings-Reference.md did not list it. Adds the
label and description to i18n.js, a row in the Agents & CLIs table, and a
JSDOM test that runs the real translator over the real index.html.
