fixes spraycans left-click (#93932)

## About The Pull Request
The spraycans were rendered unable to paint some items via left-click,
it forced the use of right-click which paints all over the object
instead of primary parts.
## Why It's Good For The Game
Crayons are available everywhere to rename stuff, the spraycan
left-click recoloring shouldn't have vanished so soon

Here's an example:

The regular det's revolver:
<img width="67" height="66" alt="image"
src="https://github.com/user-attachments/assets/6b6c422b-ecbd-4ed5-adf0-0b5c524204db"
/>

Spraycan left-click:
<img width="65" height="68" alt="image"
src="https://github.com/user-attachments/assets/b3b952f2-ac8d-42a5-8805-d41b9ef42125"
/>

Spraycan right-click:
<img width="65" height="63" alt="image"
src="https://github.com/user-attachments/assets/c5c6f7d6-da91-48c9-a920-278939ff2f0a"
/>

And crayons/pen can still be used to change description and name.
