i18n(update): translate the Buzz download price strings

Completes the 13 keys the obtainability feature left as [TODO: Translate], in all
9 locales: the two gate-event counts, the sale / Blue Buzz / "Free Now" / early
access end-date badge strings, and the six settings.priceTracking strings plus the
section header.

- Buzz and Blue Buzz stay as-is everywhere: they are CivitAI currency names, not
  translatable words (R3)
- register follows each file's existing norm (你 zh-CN, 您 zh-TW, Sie de, tú es,
  вы ru); fr keeps the file's ASCII apostrophe style; no full-width punctuation
  leaked into the Latin/Cyrillic/Hebrew locales
- two source fixes came with the pass: the unused settings.priceTracking.label key
  is removed (no template renders it - the toggle uses enabled/enabledHelp), and
  settings.sections.priceTracking now reads "Buzz Download Prices" so the header
  matches what the feature does: prices are displayed, nothing is tracked for
  alerts
- the locale files were edited by exact-value replacement rather than re-serialised,
  so each diff is 13 lines and the per-file indentation is untouched (R1)
