  Returns the most recent samples for `monitor_id` across the cluster.

  Each sample is returned as a plain map with the following keys:
    * `:monitor_id` - the monitor's string ID
    * `:instance_id` - the instance ID (string/binary)
    * `:status` - string representation of the health status (e.g., "up", "down", "degraded", "unknown")
    * `:latency_ms` - nullable integer representing latency
    * `:status_code` - nullable integer representing status code
    * `:metrics` - map of numeric metrics
    * `:collected_at` - UTC DateTime of the sample collection
    * `:synthetic` - boolean indicating if this is a synthetic sample
