### Description of PR
Retrieving the logs for a running application fails as the logs CLI expects
a JSON object as a response when calling the NM REST API, and it provides a
JSON Array
Actual response with Jersey 2:
```
[
{
"containerLogsInfo": {
"containerLogInfo": [
{
"fileName": "stderr",
"fileSize": "0",
"lastModifiedTime": "Wed Nov 12 13:26:19 +0000 2025"
},
...
],
"logAggregationType": "LOCAL",
"containerId": "container_e80_1762940127665_0015_01_000003",
"nodeId": "ccycloud-2.native-moxy4.root.comops.site:8041"
}
}
]
```
Expected response with Jersey 1:
```
{
"containerLogsInfo": [
{
"containerLogInfo": {
"fileName": "logfile1",
"fileSize": "12",
"lastModifiedTime": "Thu Nov 13 13:11:14 +0100 2025"
},
"logAggregationType": "LOCAL",
"containerId": "container_0_0000_00_000000",
"nodeId": "testhost.foo.com:8042"
},
{
"containerLogInfo": {
"fileName": "logfile1-aggregated",
"fileSize": "23",
"lastModifiedTime": "Thu Nov 13 13:11:14 +0100 2025"
},
"logAggregationType": "AGGREGATED",
"containerId": "container_0_0000_00_000000",
"nodeId": "testhost.foo.com_8042"
}
]
}
```
### How was this patch tested?
Tested on a cluster:
- Logs CLI works for running/finished applications
- UI v2 works when loading containers for a node
Response format for `/ws/v1/node/containers/{container-id}/logs` endpoint
seems compatible with the Jersey 1 format comparing them with a nightly version:
**JSON**:
```
{
"containerLogsInfo": [
{
"containerLogInfo": [
{
"fileName": "stderr",
"fileSize": "0",
"lastModifiedTime": "Wed Nov 19 08:40:57 +0000 2025"
},
{
"fileName": "prelaunch.err",
"fileSize": "0",
"lastModifiedTime": "Wed Nov 19 08:40:57 +0000 2025"
},
{
"fileName": "prelaunch.out",
"fileSize": "70",
"lastModifiedTime": "Wed Nov 19 08:40:57 +0000 2025"
},
{
"fileName": "stdout",
"fileSize": "0",
"lastModifiedTime": "Wed Nov 19 08:40:57 +0000 2025"
}
],
"logAggregationType": "LOCAL",
"containerId": "container_e87_1763463022925_0008_01_000003",
"nodeId": "ccycloud-2.native-moxy4.root.comops.site:8041"
}
]
}
```
