[Feature]: View only changed tests in UI mode

[cpAdm]

🚀 Feature Request

Add toggle in UI mode to view only changed tests (with same behavior as --only-changed CLI flag)

Example

Some examples:

Another checkbox (but probably doesn't look great on smaller screens)

Or as toolbar button:

Or still in filters section:

Motivation

Quickly being able to filter on changed spec files would be very helpful. Then no need to filter yourselves when writing/debugging certain tests, or right before you want to push code and run all your changed tests locally.

Discussed this in the team meeting. It is a low priority feature to justify a place in the main UI. Putting it to the settings menu didn't get much support either, compared to the last failed tests filter it looked more niche. We can give it a try in the filter but the chances are it will be reverted during review.
