feat(web): add error boundaries, loading skeletons, render fixes and tree-shaking

- Add error.tsx to all 13 route groups: admin, allocations, analytics, dashboard, estimates, notifications, projects, reports, resources, roles, staffing, timeline, vacations
- Add loading.tsx to 9 routes that were missing them: admin, analytics, dashboard, estimates, notifications, reports, roles, staffing, vacations
- ResourceDetail: wrap vacationStart in useMemo to stabilize query key, remove dead windowEnd variable
- node-renderer.ts: replace barrel import (import * as THREE) with named imports for tree-shaking
- next.config.ts: add framer-motion and @capakraken/shared to optimizePackageImports
