Use subPath mounts for Homepage config files

Homepage tries to copy skeleton files (custom.css etc.) into /app/config
at startup. A ConfigMap volume mount makes the directory read-only,
blocking this. SubPath mounts keep individual config files from the
ConfigMap while leaving the directory writable.
