feat: update auth provider to not refresh token every 2 minutes

[RMCampos]

This pull request removes the logic for periodically refreshing the user session token in the AuthProvider component. The code responsible for setting up and clearing an interval to refresh the token every two minutes has been deleted, simplifying the authentication context.

Authentication session management:

• Removed the intervalInstance state and related logic for setting up a periodic token refresh using setInterval, including the refreshTokenPvt function and the associated useEffect hook. Now, the user session will no longer be automatically refreshed at regular intervals. [1] [2]
• Cleaned up the logout process by removing interval cleanup logic, as it is no longer needed.
