fix: correctly call the /variable endpoint after the user is authenticated (#4267)

* ✨ (authContext.tsx): Add functionality to fetch global variables on authentication
🔧 (api.tsx): Replace universal-cookie import with react-cookie for consistency
🔧 (authStore.ts): Replace universal-cookie import with react-cookie for consistency
🔧 (use-get-global-variables.ts): Add check to only fetch global variables if user is authenticated
✨ (use-get-mutation-global-variables.ts): Add mutation function to fetch and update global variables
🔧 (authStore.ts): Replace universal-cookie import with react-cookie for consistency

* ✨ (use-get-folders.ts): add authentication check before fetching folders data to ensure only authenticated users can access the data
