Returns datasource integrations for the authenticated user's organization.

Deprecated: Omitting pageNumber and pageSize returns the full list. This unpaged behavior is deprecated and will be removed in a future release. Provide both parameters to request a single page. Unpaged requests remain supported for backward compatibility.

pageNumber is one-based (the first page is 1), consistent with PagingOptions. Clients paging this endpoint should treat an empty page as the stop condition (not merely a short page), because concurrent inserts or deletes between requests can shift offset windows and there is no total-count metadata in the response.
