Add API endpoints for status and info

[Copilot]

Adds RESTful API endpoints to the vulnerable-node application for querying system status and application metadata.

Changes

• New endpoints:
  • GET /api/status - Returns runtime status with timestamp
  • GET /api/info - Returns application metadata and available endpoints
• New route module: routes/api.js following existing Express Router pattern
• App integration: Registered API routes in app.js alongside existing route modules

Example

$ curl http://localhost:3000/api/status
{"status":"ok","message":"API is running","timestamp":"2025-11-05T08:13:52.130Z"}

$ curl http://localhost:3000/api/info
{"application":"vulnerable-node","version":"1.0","endpoints":["/api/status","/api/info"]}
