fix(i18n): keep English pixel-identical and stored data English

From the English-parity and breakage review against main:
- English wording back to main: "Configured Source", the "SHARED SUBJECT"
  fallback, CCTV calibration "RANGE 120m".
- Voice header and CCTV calibration chip/select tweaks for long labels now
  apply to non-English only (html:not([lang='en'])); English matches main.
  The scene select font change is scoped the same way.
- New scenes and shots store their default title in English ("Scene 3",
  "Shot 2") and translate it when shown, so a title captured in one language
  does not leak into projects, storage or shared JSON.
- Choosing a language with storage blocked keeps it in ?lang instead of
  silently doing nothing.
- One picked import file shows its name again.
- qa-l9-matrix reads the voice state from data-status, not the label.
