Issue: https://linear.app/comm/issue/ENG-3014/add-a-button-to-close-the-filter-panel
There is supposed to be a button for closing the filter panel, inside of the filter panel. Additionally some styles around it were changed, so I changed them as well to keep the panel looking consistent. Note that in the issues comments it had been decided to keep the search bars background colour consistent with the rest of the app for now.
