Update halo rendering logic and conditions

Refactored method "isDisableHalo" to "isEnableHalo" in HaloRenderer class. The change in function name is also accompanied by an update in its logic – specifically related to the condition checks and setcookie values. Furthermore, adjusted the call in the 'render' function to reflect this modification. This improves the understanding and readability of the code.
