feat(ui): importer carries dat FontColor (0x1B) onto text widgets; character colors from dat where present

LayoutImporter.ReadState now reads Properties 0x1B (ColorBaseProperty, ARGB bytes) and stores the normalized Vector4 in ElementInfo.FontColor (nullable). ElementReader.Merge propagates it with the same non-null-derived-wins rule as FontDid and HJustify. DatWidgetFactory.BuildText seeds UiText.DefaultColor from FontColor when present.

Diagnosis for LayoutDesc 0x2100002E: ALL 12 header and footer text elements carry NO dat color. Every color is runtime set by CharacterStatController. Comments added at each callsite. No hardcoded colors deleted.

Tests added: 3 ElementReader FontColor Merge + 3 DatWidgetFactory DefaultColor. 702 passed, 0 failed. Screenshots: character window, vitals, toolbar all unchanged.
