Sync of entity approval status for encounter type and program should sync data linked to all subject types

Analysis details:
Currently`fetchSubjectTypeForEntityNameAndUuid` used in EntityApprovalStatusController for getting entityApprovals, fetches only the first subject type linked to encounter type or program. This results in fetching entityApprovalStatus based on only the sync settings of the first subject type. This needs to be fixed.

Start by tracing fetchSubjectTypeForEntityNameAndUuid as used by EntityApprovalStatusController, then inspect how encounter types and programs link to subject types and how sync settings determine entity approvals. Done means approval status synchronization considers data linked to all relevant subject types rather than only the first one; no test or file path is named in the issue.
