In `@src/engine/input/key_mapping/SpecifiedInputKey.cs`:
- Line 585: Update the representation-generation flow around CreateTextureRect
and KeyPromptHelper.GetPathForControllerDiagram so it does not call GD.Load for
controller diagram textures. Resolve and cache or inject both diagram textures
through the established resource-reference mechanism before creating the UI
node, then pass those references into the UI construction path.
