Stop shipping host metrics from openobserve-collector to OpenObserve

Metrics and alerting stay in kube-prometheus (source of truth + Alertmanager);
OpenObserve holds logs and traces only and should not duplicate infra metrics.

Remove the agent collector's `metrics` pipeline (kubeletstats + hostmetrics ->
OpenObserve) and the now-unused `hostmetrics` and `kubeletstats` receiver
definitions (the OTel Collector errors on components defined but not used). The
agent now runs a logs-only pipeline (filelog/std -> OpenObserve); traces are
unchanged on the gateway.

Bump openobserve-collector 0.4.5 -> 0.4.6 and openobserve 0.13.5 -> 0.13.6.
