Hardcoded Text settings

[Kirby]

Several settings like add_profile_place contain hardcoded text, which makes it difficult to create translations:

Content visible to verified customers only.

Therefore I would like to suggest to use phrases here:

Content visible to verified customers only.

Fixed and found more.
Thanks Sir.

In addition to this: Several settings are also missing the bginput class, so they do not appear styled like other controls.
