Fix Multiple Cookie Issue: Properly Handle Multiple Set-Cookie Headers in ZitiUrlProtocol

[Dicky019]

This PR addresses an issue where multiple Set-Cookie headers in HTTP responses were not handled correctly by ZitiUrlProtocol. Previously, only one cookie would be processed, causing potential loss of additional cookies set by the server.

Key improvements:

• Correctly parses and collects all Set-Cookie headers from HTTP responses.
• Merges all cookie values into a single entry in the resulting dictionary, ensuring no cookies are missed.
• Resolves issues with authentication, session management, or any functionality relying on multiple cookies.

This fix improves compatibility with servers that set multiple cookies and ensures more reliable client behavior.
Please review and let me know if further changes are needed. Thank you!
