🚨 Severity: HIGH
💡 Vulnerability: The /api/visits endpoint had Access-Control-Allow-Origin: "*" enabled, allowing any website to access visitor statistics and trigger counter increments.
🎯 Impact: Potential for data scraping or manipulation of the visitor counter by third-party sites.
🔧 Fix: Removed CORS headers and the OPTIONS handler. Restricted headers to Content-Type: application/json and Cache-Control: no-store. Corrected error response status codes to 500.
✅ Verification: Verified code changes, ran pnpm build, and checked for linting/formatting issues.

- Removed "Access-Control-Allow-Origin: *" from the visits API.
- Removed unnecessary OPTIONS handler.
- Added "Cache-Control: no-store" for better security.
- Fixed error handling to return 500 status code instead of 200.
