Subject: [PATCH] fix(prisma): mark most brand fields as optional

This patch makes most of the brand fields optional. It is better that
these are left as NULL when importing brands than for me to set them to
something nonsensical. I will gradually populate these fields as
necessary, but their initial absence shouldn't block record creation.
