Enhance /api/administration/registration/applications Endpoint

[jjeroch]

Description:
Enhance the /api/administration/registration/applications?size=10&page=0 endpoint by adding a new attribute "type" to the response, which indicates whether the application is "external" or "internal". This information is available at the application level in the database.

Acceptance Criteria:

1. Endpoint Enhancement:

   • Modify the existing endpoint to include the "type" attribute in the response.
   • The "type" attribute should have a unique value, either "external" or "internal", based on the information stored in the database.

2. Database Integration:

   • Retrieve the "type" information from the application-level data in the database.
   • Ensure the "type" attribute is properly mapped and included in the endpoint response.

3. Response Structure:

   • Update the existing response structure to include the new "type" attribute for each application in the "content" array.
   • The updated response structure should be as follows:

{
  "meta": {
    "totalElements": 0,
    "totalPages": 0,
    "page": 0,
    "contentSize": 0
  },
  "content": [
    {
      "applicationId": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
      "applicationStatus": "CREATED",
      "dateCreated": "2024-07-17T11:33:13.790Z",
      "companyName": "string",
      "companyRoles": [
        "ACTIVE_PARTICIPANT"
      ],
      "applicationChecklist": [
        {
          "typeId": "REGISTRATION_VERIFICATION",
          "statusId": "TO_DO"
        }
      ],
      "email": "string",
      "bpn": "string",
      "type": "external"
    }
  ]
}

4. Error Handling:

   • Instead of submitting an error in case no type is existing, the endpoint is supposed to respond for the type the value null

5. Documentation:

   • Update the API documentation to reflect the changes made to the endpoint, including the new "type" attribute.

6. Testing:

   • Implement unit tests to ensure the endpoint's functionality, including the new "type" attribute, works as expected
