Provisioning is create-if-absent, so a field the desired spec gained after an
install (spec.rcon, spec.startup.healthHTTPPort, a derived env key) never
reaches the existing login/lobby CR while every re-run of setup reports
success — the reported 'configuration updates never reach an installed
deployment' symptom. converge is the explicit pass: it fills exactly the
zero-valued whitelist fields and the derived env (including a missing key,
which refreshDerivedEnv deliberately never adds), and never overwrites a
non-zero value. The timing stays with the operator because enabling RCON or
the HTTP readiness gate on a pre-listener image would wedge that server in
Starting until it was marked Failed.
Tests: fills predated fields while operator edits survive / non-zero values
left alone / absent + foreign + unset-image guards. usage table updated so the
router-parity test passes; troubleshooting gains §12b.
