fix(i18n): add cache-busting version strings to privacy page scripts

SUMMARY:
Added version query strings to script tags on privacy.html to force
browser cache refresh for i18n updates.

CHANGES:
- Added ?v=20251019145500 to i18n-simple.js
- Added ?v=20251019145500 to language-selector.js
- Added ?v=20251019145500 to footer.js

IMPACT:
Users will now load the updated JavaScript that knows how to load
common.json for footer translations. Prevents stale cache issues.
