Problem

The master_stack drag-resize tests were still waiting for an exact relayout log transition even though drag-resize sync is asynchronous and already covered elsewhere with a looser at-most-one relayout contract. On CI that made the nmaster 2 path fail even when @mosaic-mfact and the later split geometry were correct.

Solution

Wait for the window fingerprint to settle after the drag-resize mfact change before asserting the synced @mosaic-mfact value and the follow-up split geometry. Apply the same stabilization to the top-orientation drag-resize case so both tests wait on settled state instead of exact relayout timing.
