🛡️ Sentinel Security Enhancement: Global Error Boundary

Severity: MEDIUM (Defense in Depth / Error Handling)

Vulnerability:
The application lacked a global Error Boundary. If a component failed (runtime error, suspense failure), the entire React tree would unmount, leading to a "White Screen of Death". In some configurations, this might also risk exposing stack traces or error details to the user, which can leak implementation details.

Impact:

Availability: One broken component crashes the whole app.
Information Disclosure: Potential leak of stack traces (though mostly a concern in dev/misconfigured prod).
UX: Poor user experience during failures.

Fix:
Implemented a ErrorBoundary class component that:

Catches errors in the component tree.
Logs them securely (to console currently, extendable to monitoring services).
Renders a generic, user-friendly fallback UI ("Something went wrong").
Explicitly does not render error.message or error.stack to the DOM.

Verification:

Added src/components/layout/__tests__/ErrorBoundary.test.tsx verifying the fallback UI appears and the error text is NOT present.
Manually verified the application still starts up correctly (home page renders) via Playwright script.
