feat(ui): importer carries dat justification (0x14/0x15) onto text widgets; drop character footer-title height hack

LayoutImporter.ReadState now reads Properties[0x14] (HorizontalJustification,
EnumBaseProperty: 0=Left, 1=Center, 3/5=Right) and Properties[0x15]
(VerticalJustification: 2=Top, 4=Bottom; else Center) into two new ElementInfo
fields HJustify/VJustify. Merge propagates them with the same non-default-wins
rule used for FontDid.

DatWidgetFactory.BuildText applies the resolved justify at build time:
HJustify=Center sets Centered=true, HJustify=Right sets RightAligned=true,
VJustify=Top/Bottom sets VerticalJustify. Controllers that FindElement and set
those properties afterward continue to override - backward-compat preserved.

UiText gains VerticalJustify (Top/Center/Bottom, default Center). The Centered
and RightAligned single-line paths call UiText.VOffset() for the Y coordinate,
so VJustify.Top renders text at y=Padding rather than the fixed (H-lh)/2 center.

CharacterStatController: footer title (0x1000024E, H=55 dat box) previously
used Height=18 + Anchors=None to prevent center-vertical overlap with line-1/2.
Diagnostic confirmed dat says HJustify=Center, VJustify=Center. The hack is
replaced with one minimal explicit override: VerticalJustify=Top on the
already-Centered element. Text now renders at top of the 55px box natively.
Centered=false and RightAligned=false hand-sets removed where dat supplies them.

Dat justify values (studio diagnostic, 2026-06-26):
  0x1000024E footer title: HJustify=Center, VJustify=Center
  0x10000235/0x10000243/0x10000245 value fields: HJustify=Right
  header name/heritage/pk/level: HJustify=Center

+13 tests: ElementReader Merge propagation; DatWidgetFactory BuildText
justify application + controller-override backward-compat; UiText VOffset.
696 passed, 0 failed.
