[Workbench] Warning message during startup for `database.conf` mount

When database.conf is defined, the below warning is triggered during startup. The permissions are correct (root:root) and likely don't ever need an update in an k8s environment. I guess the check comes from an internal WB process but is likely only relevant for non-k8s envs?

Would be good to account for it as one cannot do so because the referenced mount is initiated by the chart. AFAICS this affects all deployments which don't use the built-in SQLITE DB.

config:
  secret:
    database.conf
      provider: postgresql

Start by tracing the chart-managed database.conf mount and the warning reported from src/cpp/server_core/ServerDatabase.cpp:343. Reproduce startup with the PostgreSQL database.conf configuration, then determine how the read-only mount is handled; done means the deployment no longer emits this misleading warning while preserving the stated ownership check.
