feat: Make summary for pre-messages look like summary for fully downloaded messages (#7775)

This is not possible for webxdcs and vCards currently however, so add workarounds for them:
- Use translated "Mini App" as the webxdc name.
- Use just "👤" instead of the vCard summary (i.e. the vCard contact name).
