During our Liquid Glass update, we agreed on having the "close" button always on the top left (like in Apple Music), unless it is part of a flow that causes it to move to the other side (e.g. a back button). We have this on most of our screens now. However, the Customize screen of the Activity tab is breaking this rule. This task is to update that.
User story: as a user, I want to navigate between screens and dismiss modals without losing my place or having to search for controls, so that I can move through the app quickly and confidently.
