i18n: catalogue entries for the context menu, PLINE and modify options

Every new UI string (menu rows, Options → Right-click Customization, the
PLINE sub-prompts and keyword labels, MOVE/COPY/OFFSET prompts) gets its
Fluent attribute in all 21 locales plus the source → attribute rows in
locale_catalog.rs; the SETVAR help line lists SHORTCUTMENU and
SHORTCUTMENUDURATION. Tests that compared prompt text now check command
state so they pass under any UI language.
