fix(node): bound the invalid Hash echoed in the add error

The pin_git_object CID validation rejects non-CID Hash strings, and a
dozen test_support fixtures answered 200 with placeholder values like
"bafyprovider" or "x". Replace them with a valid CID so the fixtures
model a healthy backend; no test asserts on the literal value.
