feat(federation): GSAP-powered 3D orbital node map, fills viewport to bottom

- Add gsap 3.15 + design-system-aware motion module (src/utils/motion.ts):
  shared colour/duration/ease tokens mirrored from style.css, gsap.defaults,
  live prefers-reduced-motion check.
- Replace the d3 force NetworkMap with NetworkMap3D.vue: peers on projected
  3D orbital rings around the self node, cinematic intro (camera dolly +
  staggered fly-in + ring draw), idle rotation with drag-to-orbit inertia,
  depth-sorted painter's order, trust-colour palette, online/offline states,
  sonar pulse on self, tap-a-node opens the detail modal.
- Map view now fills the dashboard panel to the bottom edge on desktop,
  mobile and companion: .dashboard-scroll-panel:has(.node-map-stage) turns
  the panel into a column (tab-bar/safe-area/audio-player aware padding)
  instead of leaving the old dead bottom margin.
- Reduced motion: intro/idle skipped, scene renders static.
