Properties: Implement container queries

[nielslyngsoe]

Fixes #18983

Implement container queries, so properties go into 'vertical layout' when there is less than 700px available for them.

[Copilot]

Pull Request Overview

This PR implements container queries for the property layout system to enable responsive behavior. Properties will automatically switch to a vertical layout when less than 700px of horizontal space is available, improving the user experience on smaller screens or narrow containers.

• Enables container queries by adding container-type: inline-size to property layouts
• Updates breakpoint threshold from 600px to 700px across property layout components
• Uncomments previously disabled container query CSS rules to activate responsive behavior

Everything looks good with the container queries! 👍
While testing, I noticed something unrelated to your changes: when the container query kicks in, in the content type design, the property editor name gets cut off if it has extra tags like the mandatory indicator. Should we fix this in this PR, or would you prefer a separate issue since it's not related to the goal of the container query update?

Great! It works as expected
