Code-review follow-up to PR10b-e:
- DetailHeaderStrip + KPITile: border-slate-200 → border-border so dark
mode doesn't paint a bright halo around the gradient strip.
- Topbar avatar: ring-white → ring-background so the 2px ring tracks
the surface (matches the sidebar footer pattern).
- KpiTileSkeleton stripe: bg-slate-100 → bg-muted for parity with
shadcn skeleton tokens in dark mode.
- Sidebar <aside>: add `relative` so the absolute-positioned
collapse-toggle button anchors to the sidebar itself rather than
the nearest positioned ancestor.

Adds the design tokens the polish PRs (10a-e) will draw from:
shadow-xs/sm/md/lg/glow, radius scale tuned to spec, gradient utilities,
spring/smooth eases, and fast/base/slow durations. Introduces
StatusPill, KPITile, and EmptyState primitives plus a polished
PageHeader variant ('gradient') with optional eyebrow + KPI sub-line —
existing PageHeader callers stay on the plain variant.
