🛡️ Sentinel: [CRITICAL/HIGH] Fix XSS vulnerability in email preview

[brycejohnson1417]

🚨 Severity: HIGH
💡 Vulnerability: Used dangerouslySetInnerHTML to render email preview in components/accounts/ppp-savings-panel.tsx, which can expose the application to potential XSS attacks.
🎯 Impact: An attacker could inject malicious scripts into the email preview, which would execute in the victim's browser context.
🔧 Fix: Replaced dangerouslySetInnerHTML with an iframe leveraging the srcDoc attribute and a sandbox attribute (sandbox="allow-popups allow-popups-to-escape-sandbox"). Injected styles inline into the srcDoc HTML string to maintain the UI styling.
✅ Verification: Ran npm run lint, npm run typecheck, tenant-isolation checks, and visually verified the UI via Playwright script, ensuring the iframe renders properly and the UI isn't broken.
