fix(D.2b): correct edge-anchor mapping (RightEdge==1=stretch) + enable vitals horizontal resize

ToAnchors was inverted vs retail UIElement::UpdateForParentSizeChange @0x00462640:
stretch is RightEdge==1 (not ==2/==4), LeftEdge==2 = track-right. Verified against
all 19 vitals fixture pieces. Enables Resizable/ResizeX on the importer vitals root
(the prior 'dat is fixed-size' conclusion was wrong). At-rest render unchanged
(anchors only fire on resize). Added a 160->200 resize conformance test.
Also fixed DatWidgetFactoryTests.RectAndAnchors_SetFromElementInfo which encoded
the old inverted model (Right=2 expecting Right anchor; corrected to Right=1).
