Manish Gupta ea8a66719f [WEB-8332] fix: validate role before guest-cascade, make it atomic (Copilot #9460) ...

partial_update cascaded the guest project-role downgrade BEFORE the serializer
was validated/saved, using a manual int() cast that 500s on non-integer input.
Reorder: validate the serializer first, then cascade using
serializer.validated_data["role"] inside a transaction.atomic() with save(), so a
bad role returns 400 (not 500) and project roles can't be downgraded when the
member update doesn't persist. Adds a non-integer-role 400 test.
