feat(D.2b): vital bars use retail dat sprites (back track + fill-cropped front)

Browse source 
UiMeter gains SpriteResolve/BackSpriteId/FrontSpriteId; when both are
set, OnDraw draws the empty-track sprite full-width then the colored-fill
sprite UV-cropped to the live fill fraction (left-to-right drain). Falls
back to solid rects when sprite ids are absent, keeping existing behavior
and tests intact.

MarkupDocument.Build() parses `back`/`front` hex attrs on <meter> and
passes `resolve` into every UiMeter.  vitals.xml wires the authoritative
LayoutDesc 0x21000014 sprites (Health 0x06005F3C/3D, Stamina 3E/3F,
Mana 40/41).  The bar prove-out block in GameWindow.cs was already gone.

If the sprites decode as 1x1 magenta at runtime they are paletted
(INDEX16/P8) — the solid-color fallback will display instead and can be
investigated separately.
