Add an at-risk vault highlight to the Dashboard using deadline urgency tiers

[1nonlypiece]

📌 Description

src/components/VaultCard.tsx exposes deadlineUrgency tiers (safe/soon/
critical), but the Dashboard doesn't surface a focused "needs attention" view —
active vaults nearing their deadline are buried in the general list.

This issue adds an "at-risk" highlight section listing vaults whose deadlines are
critical/soon and that are still active or pending validation.

🎯 Requirements and Context

• Add src/utils/atRiskVaults.ts selecting vaults by urgency tier + status.
• Render an "At Risk" section on Dashboard.tsx using VaultCard.
• Hide the section when nothing is at risk.
• Reuse deadlineUrgency (export it from VaultCard.tsx if needed).

🛠️ Suggested Execution

1. Fork the repo and create a branch

git checkout -b feature/dashboard-at-risk

2. Implement changes

• Create src/utils/atRiskVaults.ts; add the section to Dashboard.tsx.
• Add src/utils/__tests__/atRiskVaults.test.ts.
• Update src/pages/__tests__/Dashboard.test.tsx.

3. Test and commit

• Run npm test.
• Cover edge cases: nothing at risk (hidden), completed vaults excluded,
  critical vs soon selection, expired deadlines.
