feat(frontend): micro-interactions — page-enter transition + MetricTile lift

- Add animate-fade-up utility (reduced-motion aware) and a PageTransition
  wrapper; every dashboard view now rises + settles on mount/route change.
- MetricTile gains a subtle hover lift (-translate-y) + ring-focus glow.
- Theme toggle and command palette (⌘K) already existed and persist; no-op.
