Subject: [PATCH] Do not remove policy levels when traffic statistics is
 disabled (#6146)

Disabling traffic statistics removed the whole policy section from the
generated config, including the levels block (uplinkOnly, downlinkOnly,
connIdle, handshake) from the template or from a user's custom config.
Only the stats-related policy.system block should be stripped; keep
policy.levels intact in both the unified and the custom config paths.
