fix: UCS FACE/OBJECT pick from the interactive prompt; reuse ocs_axes

Follow-up to #1341:
- interactive UCS offers Face / OBject; bare UCS OBJECT starts an entity pick
- one UcsPickCommand serves both FACE and OBJECT
- ucs_from_normal calls the existing arbitrary-axis helper instead of a copy
- prompt catalogue key and en-US text follow the new option list
