fix: catalog every ported web string in all locales; drop tests of unported STB parsing

- Translate the strings the #1717 port cataloged in English only
  (CSV picker, plot-preview task, extraction cap, shared-copy warning)
  for every locale, and the whole ported web set for lo-LA, which the
  contributor branch predates.
- hu-HU carried twelve keys twice after the port's merge; keep main's.
- The STB container/refusal tests exercised parsing this port did not
  bring over; the preview-clamp test now only pins the upper bound, since
  main's raster path already clamps preview pages further.
