Generate Sprite "Generate" button tooltip displays raw internal validation string instead of a user-friendly message

Usability

Third Party Issue

2.8.X

Thank you for reporting a bug to Unity. Our investigation indicates the issue originates from a third-party asset, plugin, or service, rather than Unity itself. Because the problem lies outside our codebase, we're unable to address it directly. We will close this case as a third-party issue. We recommend contacting the vendor or maintainer for support. If you have evidence that the issue is within Unity, please share it and we will re-open the investigation.

Steps to reproduce:
1. Create new Unity project using Universal 3D Template 
2. Install AI Package via toolbar AI button
3. Go to Assets > Create > 2D > Generate Sprite
4. Hover over “Generate” button
5. Observe the tooltip

Actual results: Tooltip on the "Generate" button displays a raw internal validation string ("Prompt: string_lengt: String is too short")

Expected results: Tooltip on the "Generate" button displays a clear, user-friendly message (e.g., "Prompt is too short")

Reproducible with versions: 2.8.0-pre.1 (6000.0.76f1, 6000.3.16f1, 6000.4.8f1, 6000.5.0b9, 6000.6.0a4)

Tested on (OS): macOS Silicon Tahoe 26.4.1 (M1)
