Closes #494 — Refactor Rate Limiter Configuration into a Dedicated Middleware Module

✅ Changes Made

• Extracted the rateLimit configuration logic from app.js.
• Created a new ES Module file: middleware/rateLimiter.js.
• Exported the configured limiter instance using export default.
• Imported the limiter into app.js and applied it using app.use("/api", limiter);.

🧪 Testing Checklist

• Server starts successfully without errors.
• The /api routes are correctly rate-limited to 1000 requests per 15 minutes.
• The existing rate-limiting behavior remains completely unchanged.

📌 Benefits Achieved

• ✅ Cleaner app.js entry point.
• ✅ Better Separation of Concerns (Rate limiting logic is isolated).
• ✅ Easier reuse across different routes in the future if needed.
