feat(insights): replace fixed overviews with a single arrangeable overview
Categories, Tags and Entities Overview are merged into one Overview page. Levels are chips that can be dragged (or moved with the arrow keys) to set the hierarchy and clicked to switch off, so any ordering of the three is reachable from the same page. Only the results reload on change; the controls stay in place. The chip order is kept in the session and defaults to categories by tags, matching the old Categories Overview.
