prometheus: remove obsolete host Immich scrapes

 The `resources/` directory contains cluster-specific alert rules that are not
 chart defaults. It does not contain application workload templates. Immich's
-host metrics endpoints are configured as static scrape targets in `values.yaml`;
-this avoids depending on legacy Endpoints objects, which this Argo CD instance
-intentionally excludes from reconciliation.
+in-cluster metrics endpoints are discovered through its ServiceMonitor in the
+Immich namespace; the former host scrape targets were removed after migration.
 
 The chart's CRDs are skipped during normal sync because the existing CRDs are
 cluster-wide and their large schemas exceed client-side apply annotation limits.
