feat(D.2b): per-window resize-axis lock; vitals window is X-only (retail)

Browse source 
Add ResizeX/ResizeY bool properties to UiElement (both true by default).
HitEdges() in UiRoot masks out locked axes after edge detection, so a
locked edge falls through to window-move behaviour — matching retail,
where the vitals bar height is fixed and only widens.

MarkupDocument.Build() parses an optional resize="x|y|both|none"
attribute on <panel>; vitals.xml gets resize="x" to enforce the
horizontal-only constraint in all instances of the panel.

Two new tests: HitEdges_RespectsResizeAxisLock (UiRootInputTests) and
Build_ResizeAttrX_SetsHorizontalOnly (MarkupDocumentTests). 11/11 green.
