Update the v-server, enable cors

[Mahmoud-Emad]

Description

Enable CORS in the Vlang server for the /api/verify endpoint. This pull request addresses the CORS issues related to preflight (OPTIONS) and actual POST requests.

Changes

1. Preflight Handling (preflight function):

   • Added the 'Access-Control-Allow-Headers' header to allow 'Content-Type' in the preflight response.
   • Ensured 'Access-Control-Allow-Origin', 'Access-Control-Allow-Methods', and 'Vary' headers are set.

2. POST Request Handling (verify function):

   • Set 'Access-Control-Allow-Origin' header in the response for the actual POST request.

Related Issues

• Enable CORS in v-server UI package #1547

Additional Notes:

• The 'Access-Control-Allow-Origin' header is set to '*' for allowing any origin.
• Tested and verified the changes to resolve CORS issues.

Checklist

• Tests included
• Build pass
• Documentation
• Code format and docstrings
• Screenshots/Video attached (needed for UI changes)
