fix(tiktok): align UX strings and render processing notice for app review

Match the literal copy the TikTok app reviewer looks for during the
Content Posting API audit, per the Mixpost playbook (the only public
account of how to pass).

- Privacy dropdown placeholder: "Select who can view this post"
- Tooltip on interaction toggles disabled by creator: "Turned off in
  your TikTok account settings"
- Render the "may take a few minutes" notice that was translated but
  never displayed (processing_hint)

Mirror both i18n changes in pt-BR and es. Add a feature test that locks
the literal strings so they cannot drift before the next review cycle.
