i18n(he): complete and ship Hebrew

- Add the full catalog (2940 entries keyed by the English text; 75 plural
  entries carry one/two/other per Intl.PluralRules('he')), reviewed for
  meaning, terms, separators and label length.
- Register he: he-IL and he map to it; it joins RTL_LOCALES so <html
  dir=rtl> mirrors the chrome through logical properties and rtl.css.
- rtl.css: Noto Sans Hebrew (loaded with the other Google fonts) leads the
  mono and sans stacks, tracking released like Arabic, HUDs keep JetBrains
  Mono for Latin telemetry.
- same-as-english: instrument codes and HUD readouts stay as printed
  (HDG/BRG/CRS/FOV/CRT/NVG/FLIR/CAL/SRC, MW units, Sentinel-2, km/h...).
- docs/translations/he.md: style, plurals and glossary.
- docs: TRANSLATORS.md and CURRENT-STATE.md updated; normalizeLocale test
  covers he-IL.
