/**
 * Cloud-agent credentials CRUD + migration coverage.
 *
 * Release/v3.8.2 review finding: the `cloud_agent_credentials` table used to be
 * created inline via `ensureCredentialsTable()` on every call (violating the
 * versioned-migration policy). That inline DDL was removed in favor of
 * migration `061_cloud_agent_credentials.sql`. These tests prove the table is
 * provisioned by the normal DB-init migration run and that encrypt-at-rest
 * CRUD still works end to end — with NO lazy table creation.
