Keep help text from following an input, so Bitwarden stops reading it as a label

Scopes on Admin → SSO still opened Bitwarden's menu after its placeholder
went, offering a "New identity".

Bitwarden takes the text after a field as part of the field's label, and in
the form theme the help paragraph was the input's next sibling. The Scopes
help explains the `email` scope and says the word twice, which made the
field an identity's email address — whatever autocomplete and data-bwignore
said on the input itself. The diagnosis came from inspecting the live page;
the placeholder removed in the previous commit was a second place the word
stood, not the one that mattered.

form_row now puts the widget in an element of its own, so nothing follows an
input as a sibling. `display: contents` on the wrapper, so the row lays out
exactly as before: measured 8px above and below the input, full width,
unchanged. This covers every field with help text, not this one.

Not checked against Bitwarden itself, which this environment does not have.
