Editor: rework default layout to UE5 arrangement

Browse Source 
Panels renamed to UE semantics (docking identity change): Hierarchy ->
Outliner, Inspector -> Details, Asset Browser -> Content Browser.

Default DockBuilder layout now matches UE5 factory layout: Details
docked right (full height), Content Browser docked bottom spanning
left+center, Outliner top-left, Viewport center with Stats as a
side tab.

Legacy imgui.ini (old window names, no new names) is removed once at
Init so the new default rebuilds cleanly; fresh or new-style ini is
untouched.
