Scale Mode is set to Constant Physical Size by default in Panel Settings Asset

Steps to reproduce:
1. Create a new project
2. In Project window create Create > UI Toolkit > Panel Settings Asset
3. Select the new created Panel Settings Asset 
4. Observe the default setting for Scale Mode

Actual results:
Having Constant Physical Size as the default setting when creating a new Panel Settings Asset can be very confusing for the user why the UI is not aligning with the game view when creating any responsive app/game.

Expected results:
Scale With Screen Size in the default option when creating a new Panel Settings Asset

Reproducible with versions:
6000.3.0b3

Tested on (OS):
MacOS Sequoia 15.6.1
