chore(window): trim the winstate diagnostics now the fix is confirmed

The traces did their job: hwnd=657868 vs form=657842 proved Win+D minimises
the FMX taskbar proxy, not the form — which is why the earlier HWND filter
swallowed every event. Two full cycles then showed minimise start/end firing
and the re-maximise landing, with no stray "user resize" during the restore.

Keeps the two lines worth having: the hook install result (a silent failure
would be baffling) and the correction itself, which is rare.
