## Summary

<!-- What changes, and why. -->

## Related issues

<!-- e.g. Closes #123. Leave blank if there are none. -->

## Translations

<!--
  Nine languages ship alongside English, and a missing key silently renders
  its English source -- so an untranslated string is invisible until somebody
  reading that language finds it. Say which this PR is, explicitly:

  - Adds or alters user-visible strings: how many keys, and the fallback
    count before and after.
  - Adds none.

  "Adds none" is an answer. Saying nothing is not -- it leaves it to be
  inferred. See CONTRIBUTING.md -> Translations.
-->

## Testing

<!--
  What you ran, and what you saw. `npm run typecheck`, `npm test` and
  `npm run build` all run in CI, so the useful thing here is what CI cannot
  do: which flows you exercised by hand, and against what -- a real Stalwart
  instance, or `npm run dev:mock`.

  If the change is visible on screen, drive the built app, not just the
  store. See CONTRIBUTING.md -> Verifying UI work.
