[TASK] Align form fields in modules 'TypoScript' and 'Page TSconfig'

With this patch we now stricly use .form-label as class for form field
labels in both modules.

The width of the option fields in both modules has been optimized for
a responsive display.

Some wrapping div's with no uses have also been removed.
