Refactor interaction prompt system to use world space prompts

- Removed the InteractPromptWidget from HUD and its references in HUDController.
- Introduced IInteractPromptView interface for world space interaction prompts.
- Implemented WorldInteractPrompt class to manage display of interaction prompts in world space.
- Updated InteractableDetector to handle showing/hiding of world space prompts based on player proximity to interactable objects.
- Created a new prefab for UI_WorldInteractPrompt to facilitate the new interaction prompt system.
