Minor - Améliore la gestion des entités ImGui - V14.8.0

Optimizes entity list updates in the ImGui interface by caching entity names and IDs.

This reduces unnecessary string operations during rendering and improves performance, especially when dealing with a large number of entities.

The initial ImGui window size has also been reduced for performance reasons.
