Refactor /query/data Endpoint and Remove Obsolete /query/data/{queryId}

[Shayan1375]

ToDo

1. Endpoint Update:
   The endpoint /query/data should return the following JSON Array object:

   {
       "id": 1,
       "comment": "Lorem ipsum",
       "createdBy": "fc846e87-6ed6-43f7-83af-72537a2ead19",
       "label": "test1111",
       "lastModified": "2025-09-19T12:09:24.023006Z",
       "ccdl": {
           "exists": true,
           "isValid": true
       },
       "dataExtraction": {
           "exists": true,
           "isValid": true
       },
       "resultSize": 0
   }
   
   

Notes:

• The lastModified timestamp should follow ISO 8601 format. Please verify if this is already implemented.
• The field ResultSize should be renamed to totalNumberOfPatients — this aligns with the naming convention used in the endpoint /query/feasibility/{queryId}/summary-result.
• Add comment to the object
• Add createdBy to the object

2. Endpoint Removal:
   The endpoint /query/data/{queryId} is obsolete and can be safely removed.

The mentioned field in summary-result will be renamed to resultSize instead. This will also be changed in the terminology search results (another time) where it is mostly "totalHits" so that we use "resultSize" everywhere.

The query endpoint will not be instantly removed but be marked as deprecated
