added analytic empty-state

[Jumongweb]

Summary

This PR hardens wallet balance handling, improves Create Vault form accessibility, respects reduced-motion in notifications, and adds empty states for Analytics periods with no chart data.

What changed

• Validate Horizon USDC balance strings before returning them to wallet UI state.
• Preserve the existing 0.00 fallback for accounts without the Circle USDC trustline.
• Add coverage for malformed Horizon balance payloads.
• Ensure CreateVault invalid fields expose aria-invalid="true" and reference their inline errors through aria-describedby.
• Add an error summary and focus the first invalid field on failed form submission.
• Extract a shared usePrefersReducedMotion hook and use it to suppress NotificationIcon dropdown motion when reduced motion is preferred.
• Detect empty Analytics period series and render a shared No data for this period placeholder instead of empty charts.
• Document the wallet-balance, field accessibility, and analytics empty-state guarantees in the design-system docs.

Testing

• Targeted tests passed for:
  • Horizon balance validation
  • CreateVault accessibility wiring and focus management
  • Reduced-motion hook and NotificationIcon behavior
  • Analytics empty-state rendering and period switching

Notes

• The full repo test suite still has unrelated pre-existing failures outside this PR’s scope.

Analytics now lazy-loads jsPDF on main, which conflicts with this PR's top-level import approach. please rebase onto current main (keeping the lazy import) and re-push, then i'll land it. https://discord.gg/xvNAvMJf

this one collides hard with analytics + create vault work that already landed on main — your version rewrites the same pdf export and create-vault flow rather than adding to them, so it won't merge cleanly. could you rebase on latest main and rework on top of the current implementations? happy to take another look after. shout in https://discord.gg/xvNAvMJf if you want to talk it through.

[Jumongweb]

Rebased onto latest main, kept the lazy jsPDF import, and reworked the create-vault changes on top of current main. The branch is pushed and the PR is updated.

nice, the empty-state placeholder reads much cleaner than bare axes. merged
