Add feature logout SSO & enable login SSO in production

[newarifrh]

This pull request includes changes to enable SSO (Single Sign-On) functionality and refactor the logout process in the authentication context. The most important changes include updates to environment configuration files and modifications to the AuthContext.tsx file to remove the old logout API call and redirect to the SSO logout URL.

Enabling SSO:

• .env: Added VITE_HAS_LOGIN_SSO environment variable set to true.
• .env.production: Changed VITE_HAS_LOGIN_SSO environment variable from false to true.

Refactoring Auth Context:

• src/contexts/AuthContext.tsx: Removed logoutApi import as it is no longer used.
• src/contexts/AuthContext.tsx: Updated the logout function to redirect to the SSO logout URL instead of calling the old logout API.
