feat: implement stage transition for ghost eaten pause and add TimeToLive component

Browse Source 
- `StageTransition` enum allows for collision system to apply state transition for ghost pausing.
- Added `TimeToLive` component & `time_to_live_system` to provide temporary sprite rendering of bonus sprites.
- Updated `stage_system` to handle the new ghost eaten pause state, including freezing entities and spawning bonus points.
