Minor - Améliore la gestion des entités ImGui - V14.9.0

Optimizes entity management in ImGui by deferring updates to the entity list until necessary.

Changes include:
- Sets the entity list as dirty upon adding or deleting entities to ensure the list is only updated when needed
- Changes the type of entity ID stored in CachedEntity
- Adjusts ImGui window size
