Improvements and fixes included in this update

4653617:
This update resolves an issue in SQL Server Analysis Services where Row-Level Security (RLS) filters could be skipped when combined with Object-Level Security (OLS) and Column-Level Security (CLS) in certain multi-role configurations. This only occurs under rare and contradictory setups (for example, a role granting table-level read permission while restricting all columns, combined with other similar restrictive roles). The fix ensures RLS is consistently applied in all scenarios.
