Anso 4d9617a5c6 feat(frontend): add SystemSheet primitive and migrate mesh sheets to §9.11 chrome (#960)
DESIGN.md §9.11 codifies one canonical right-side detail-sheet shell (cyan
rail, mono crumb, italic serif name, mono meta, ESC chip + close glyph,
fixed three-slot toolbar, cyan-underline tabs, ScrollArea body, footer
freshness band). Today the 16 sheet consumers each render their own
header chrome with stock shadcn SheetHeader/SheetTitle.

Introduce <SystemSheet> + <SheetSection> in
frontend/src/components/ui/system-sheet.tsx, composing the existing
<Sheet>/<SheetContent> primitive. Add a backward-compatible showClose
prop to SheetContent so SystemSheet can render its own ESC chip + close
glyph instead of the stock cyan square close.

Migrate the four mesh sheets as the first batch:
* MeshActivitySheet: crumb Fleet › Mesh › Activity, footer freshness from
  most-recent event timestamp.
* MeshOptInSheet: crumb Fleet › Mesh › {nodeName}, meta of opted-in
  count, drops the redundant bottom Close button (ESC chip dismisses).
* MeshDiagnosticsSheet: removes the icon-prefixed title (forbidden by
  §9.11), lifts Refresh/Restart buttons from the body into the toolbar
  band, three SheetSection blocks for sidecar status, streams, cache.
* MeshRouteDetailSheet: adds Overview/Events/Raw tabs, lifts Test probe
  into the toolbar primary slot, footer surfaces last probe latency.
