The controller reads its credentials from files; every other env-file secret says why

ADR 0086. mesh-controller mounts its six own secrets and names them with
_FILE twins, so no credential of its own reaches its environment. The 35

secrets-in-environment with the reason; converting each where its software
accepts a path is the per-module work of issue 041.
