chore(credentials): drop dead createWorkspaceCredentialBodySchema + updateWorkspaceCredentialBodySchema

Both shadowed the actually-used schemas (createCredentialBodySchema /
updateCredentialByIdBodySchema) and were missing the apiToken/domain
Atlassian fields. A future change could pick the wrong one and silently
drop those fields. Confirmed zero non-definition references in the repo
(grep across apps/, packages/, scripts/ minus build artifacts).
