Symfony's required default forced an answer to every question no matter
what the mandatory checkbox said. Optional choice questions now offer a
dedicated 'Keine Antwort' option, optional range and text questions a
'Keine Angaben machen' checkbox (preselected for ranges, because a slider
always submits a value); the side that is not chosen gets dimmed but stays
clickable. Mandatory ranges start their value display at '?' and reject
the submit until the slider was actually used, so the browser's midpoint
default no longer leaks into the results.
Empty answers are stored as a deliberate 'no answer', kept out of counts,
averages and charts, and reported separately on the results page and in
the PDF export. Also gives the reader textarea its full width and field
styling, adds grid overflow guards for unbreakable content and styles the
form error box.
