<issue_title>🛡️ Implement React 19.x error boundaries for all widgets</issue_title>
<issue_description>## 🎯 Objective
Implement React 19.x error boundaries for all widget components to provide graceful error handling and improve application resilience for v1.0 release.

📋 Background

React 19.2 is deployed but widgets may lack comprehensive error boundaries. Error boundaries prevent entire application crashes when individual widgets fail and provide better user experience with fallback UI. The project already uses react-error-boundary package.

📊 Current State

React Version: 19.2.0 (latest)

Error Boundary Package: react-error-boundary 6.0.0 installed

Current Error Handling: May be incomplete across all widgets

Widget Count: Multiple widgets in src/components/widgets/

User Impact: Widget errors could crash entire application

✅ Acceptance Criteria

Wrap all widget components in ErrorBoundary from react-error-boundary

Create fallback UI component for widget errors

Implement error logging for boundary catches

Add error recovery mechanisms where possible

Display user-friendly error messages

Include "retry" functionality in fallback UI

Test error boundaries with intentional error scenarios

Document error boundary usage pattern

Add error boundary tests (simulate component errors)

Ensure errors don't propagate to parent components

🛠️ Implementation Guidance

Files to Modify:

src/components/widgets/*.tsx - Wrap widgets in ErrorBoundary

src/components/common/ErrorFallback.tsx - Create fallback component (new)

src/components/common/index.ts - Export ErrorFallback

Widget test files - Add error boundary tests

Approach:

Create Fallback Component:
// src/components/common/ErrorFallback.tsx
import React from 'react';
import { FallbackProps } from 'react-error-boundary';

export const ErrorFallback: React.FC<FallbackProps> = ({ error, resetErrorBoundary }) => {
  return (
    <div role="alert" className="error-fallback">
      <h2>Widget Error</h2>
      <p>Something went wrong with this widget.</p>
      <pre>{error.message}</pre>
      <button onClick={resetErrorBoundary}>Try Again</button>
    </div>
  );
};
Wrap Widgets:
import { ErrorBoundary } from 'react-error-boundary';
import { ErrorFallback } from '@/components/common/ErrorFallback';

export const SecuritySummaryWidget = () => {
  return (
    <ErrorBoundary 
      FallbackComponent={ErrorFallback}
      onError={(error, info) => console.error('Widget error:', error, info)}
    >
      {/* Widget content */}
    </ErrorBoundary>
  );
};
Error Logging:

Log errors to console in development

Consider error tracking service integration point

Include component stack trace

Testing Strategy:
// Test error boundary
it('should render error fallback on error', () => {
  const ThrowError = () => {
    throw new Error('Test error');
  };
  
  render(
    <ErrorBoundary FallbackComponent={ErrorFallback}>
      <ThrowError />
    </ErrorBoundary>
  );
  
  expect(screen.getByText(/widget error/i)).toBeInTheDocument();
});
Widgets to Update:

SecuritySummaryWidget

SecurityLevelWidget

ComplianceStatusWidget

CostEstimationWidget

All other widgets in src/components/widgets/

Reusable Components:

Use react-error-boundary package (already installed)

Create reusable ErrorFallback in src/components/common/
