Revert the earlier mis-scoped orange on the personalization panel and
instead expose rgb(241,119,50) as a selectable 'رنگ اصلی' swatch. When
picked it overrides --primary/-600/-700/-soft/-soft2/-ring inline with
exact hex, so every var(--primary) consumer across the whole admin
(buttons, active nav, rings) becomes that orange. Non-fixed hues keep
the oklch hue pipeline (inline overrides removed on switch).
- uiStore: BrandHue interface + optional fixed hex; shared applyBrand()
helper handles fixed vs hue, dark-aware soft tints
- AdminLayout: reuse applyBrand() (no divergence with store)
- Topbar: swatch shows the exact fixed color
- tests: fixed-color apply, dark soft, and override-cleanup on switch
