test(stack): skip null round-trip — stack drops null support by design

stack's encrypted column type intentionally excludes null (see prior
feat(stack): remove null from Encrypted type). encrypt(null) returns
an encrypted SteVec rather than null, so the null pass-through scenario
inherited from the protect port doesn't apply. Skip it explicitly
rather than carry a forever-failing assertion.
