[UI tests] Add accessibility IDs to FancyZones to fix part UI tests (#41316)

## Summary of the Pull Request
Not sure why some text changed — for example, this button was ‘Launch
layout editor’, but in the UI it now shows as ‘Open layout editor’, so
it can’t be found :
<img width="1159" height="87" alt="image"
src="https://github.com/user-attachments/assets/d407a8fc-2876-4a85-9637-14d5923493d2"
/>

But using accessibility IDs is always more reliable.
