Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to This PR moves service authentication to a shared Kubernetes Secret and adds a migration workflow. The current migration documentation can mislead operators about Secret provisioning, so the change is mergeable with explicit owner follow-up to correct that procedure.

Description
Move the installation-scoped JWT signing identity from mutable PostgreSQL configuration to an externally persisted Kubernetes Secret and establish the clean 6.4 cutover path.
service-auth-bootstrap generate, then create the Kubernetes Secret before Helm installation.service_authrow, and configuration API writes are rejected in file-backed mode. The legacy encrypted row remains only for rollback and MEK inventory/rewrap during the rollback window.service_auth_database_write_lockand phased runtime modes are removed.The migration fails closed for missing, malformed, changing, unauthorized, or mismatched identity data. Its Kubernetes token is short-lived and its Role is restricted to
getandupdateon the named Secret. Service-auth data is excluded from configuration API responses and configuration history.The unmodified legacy
deployments/charts/servicechart temporarily retains its existing database-backed behavior when no service-auth file is configured. Removing that compatibility path must be coupled with retiring or migrating the legacy chart in the final 6.4 DB-mode removal.Validation:
