fix(security-dialog) fix form event propagation after migrating to React 17

In addition, replace the from with a div because they shouldn't be
nested.

Since we are no longer in a form, manually validate the password. This
was necessary regardless, because it was possible to bypass the digits
rule by pressing "add".
