Missing Application State Summary in /v1/partitions API in UHS

[sudiptob2]

The /v1/partitions API in Yunikorn-Core includes a summary of application states used for dashboard graphs. This information is missing in the UHS /v1/partitions API. As a result graph shown in the dashboard is incorrect in the UI served by UHS.

Example from Yunikorn-Core /v1/partitions response:

[
    {
        "id": "01JJ7NW1035Q4K9QR6XCQW510B",
        "clusterId": "mycluster",
        "name": "default",
        "capacity": { ... },
        "nodeSortingPolicy": { ... },
        "totalNodes": 1,
        "applications": {
            "Accepted": 44,
            "Running": 7,
            "total": 51
        },
        "totalContainers": 7,
        "state": "Active",
        "lastStateTransitionTime": 1737572092036846796
    }
