test(SigningRequirementValidator): add failing test for createSignature without placed elements

When admin sets GRAPHIC_ONLY render mode (canCreateSignature=true), the signer
must draw their signature even if no visual element box was placed on the
document. The previous check required visibleElements.some(...) which returned
false for documents with no placed boxes, silently skipping the drawing prompt.
