IMPORTANT CONTEXT:
This is a NextJS API route file that needs middleware added to each exported HTTP handler (GET, POST, PUT, DELETE, etc.).
The middleware must be the FIRST statement in each handler function.

Based on the route type ($middleware_type), use the appropriate middleware:

1. For 'authenticated' routes (require user login):
\`\`\`typescript
import { handleAuthenticatedMiddleware } from '@/app/api/_utils/middleware';

export async function GET(req: NextRequest) {
  return handleAuthenticatedMiddleware(req, async ({ req, user }) => {
    // Existing route logic here
    // 'user' is the authenticated UserRecord
    return NextResponse.json({ data });
  });
}
\`\`\`

2. For 'public' routes (no auth required):
\`\`\`typescript
import { handlePublicMiddleware } from '@/app/api/_utils/middleware';

export async function POST(req: NextRequest) {
  return handlePublicMiddleware(req, async (req) => {
    // Existing route logic here
    return NextResponse.json({ data });
  });
}
\`\`\`

3. For 'cron' routes (require cron secret):
\`\`\`typescript
import { handleCronMiddleware } from '@/app/api/_utils/middleware';

export async function POST(req: NextRequest) {
  return handleCronMiddleware(req, async (req) => {
    // Existing route logic here
    return NextResponse.json({ success: true });
  });
}
\`\`\`

4. For 'admin' routes (require admin role):
\`\`\`typescript
import { handleAuthenticatedMiddleware, AdminRole } from '@/app/api/_utils/middleware';

export async function GET(req: NextRequest) {
  return handleAuthenticatedMiddleware(
    req,
    async ({ req, user }) => {
      // Existing route logic here
      return NextResponse.json({ data });
    },
    { requiredRole: AdminRole.ADMIN_1 }
  );
}
\`\`\`

Additional options can be passed:
- \`context\`: String for error logging context
- \`requireCsrf\`: Boolean to enable CSRF validation
- \`requiredRole\`: AdminRole enum value for role-based access

INSTRUCTIONS:
1. Add the appropriate import for the middleware function if not present
2. Wrap the ENTIRE body of each exported HTTP handler with the middleware call
3. The middleware should return the result of the middleware function
4. Move ALL existing logic inside the middleware callback
5. Preserve all existing imports, types, and logic exactly as-is
6. If the handler already uses try-catch for error handling, you can remove it as the middleware handles errors
7. Ensure the callback parameters match the middleware type (some provide 'user', others just 'req')

Only modify the route handlers to add middleware. Return the complete fixed file."
