IIIF settings form needs to have conditional "required" fields. Only if IIIF Search API is enabled

What?

I am old. I make mistakes

The IIIF Settings (which includes now IIIF Content Search API settings) can not have required fields IF the IIIF Content Search API toggle is disabled. Does not allow saving if e.g a humble / NO OCR/ NO strawberry runners server uses recent code

No worries @DiegoPino, not the most common use case to arise. Thank you for your great work on the IIIF configurations and for fixing this minor blip in the form.

Pending. Will have to wait until 1.5.0. Sorry folks
