Adds apps/fabro-web/app/components/state.tsx exposing EmptyState,
ErrorState, and LoadingState on a shared StatePanel chrome so every
"the content isn't ready" surface looks like the same app.
Swaps in place of bare <p> tags and ad-hoc bordered divs:
- run-detail: "Run not found" is now an ErrorState
- run-stages: "No stages yet" is an EmptyState
- run-overview: empty-graph panel is an EmptyState
- run-billing: empty-billing panel is an EmptyState
- runs: filtered-empty ("no matching runs") now renders an EmptyState
(the branded landing empty is preserved as RunsLandingEmpty)
- install-app: session-loading StatusPanel replaced by LoadingState
No change to the root ErrorBoundary — full-page crashes stay there.
