Duplicate "subscriptionID" field in GET /owncompany/serviceaccounts/{serviceAccountId} endpoint

[jjeroch]

Environment:

• URL: /api/administration/serviceaccount/owncompany/serviceaccounts/{serviceAccountId}
• Release Version: unclear; likely since several releases

Description:
When calling the GET /api/administration/serviceaccount/owncompany/serviceaccounts/{serviceAccountId} endpoint, the response includes the "subscriptionID" field twice. According to the swagger documentation, "subscriptionID" should only appear once in the response.

Steps to Reproduce:

1. Authenticate with the necessary permissions to access the admin endpoint.
2. Send a GET request to /api/administration/serviceaccount/owncompany/serviceaccounts/{serviceAccountId} with a valid {serviceAccountId}.
3. Observe the response.

Expected Result:
The response JSON should contain the "subscriptionID" field only once.

Actual Result:
The response JSON contains the "subscriptionID" field twice.

User Impact:
The duplicated field may cause confusion and potentially lead to issues with systems or clients that consume this API and expect the response format to match the documentation.
