fix(i18n): Spanish review fixes; report translations left in English

A screenshot review of the Spanish UI found:

- Text left in English. Catalog entries copied from English (Bloom,
  Cyber, Pin, NEWS, SITE, ON/OFF, RANGE, PITCH, HGT…) and the radio
  music genres, which never went through t(). The genres are translated
  in es and ru now.
- Wording: gender agreement, calques of the English, hints that name
  buttons that do not exist, and one concept worded two ways.
- Layout: the DESACTIVADO pill squeezed layer names until words broke
  mid-word; the scene and camera selects showed one word; a collapsed
  rail title pushed its button out of the card; the image slot line and
  a comparison readout were cut or split.

The layout fixes are scoped to languages other than English, so English
stays pixel-identical. Visual-style slider values now use the locale's
decimal separator (0,85).

npm run i18n now reports a translation that is identical to the
English, unless src/i18n/same-as-english.json lists it for that language
(codes, product names, words spelled the same).
