v1.5.6: boneyard-js skeleton migration, TanStack Query refactor, rate-limit config

- Replace hand-coded skeleton CSS/JSX with boneyard-js auto-generated bones
- Remove skeleton.css and @keyframes shimmer from base.css
- Add <Skeleton> wrappers with fixtures to all 25+ page components
- Generate 20 bone captures via boneyard CLI (CDP auth-gated capture)
- Refactor data fetching from useEffect+useState to TanStack Query
- Extract query hooks into src/admin/lib/queries/ and apiAdapter
- Add usePaginatedQuery hook replacing useApiCall/useListData
- Fix parseFloat || 0 anti-pattern in OfferDetail and OffersTemplates inputs
- Fix customer_id mandatory validation on offer creation
- Fix leave-requests comma-separated status filter (Prisma enum in: [])
- Add cross-entity cache invalidation for orders/offers/invoices/projects
- Make rate limits configurable via env vars (RATE_LIMIT_MAX, RATE_LIMIT_REFRESH, etc.)
- Add boneyard.config.json with routes and breakpoints
