Creates sections for the insights dashboard and moves charts around into
the same order as the sketches and into the right sections. There's no
charts for the top section (lifecycle currently) yet, and the sections
also don't have their own filters.
To make this re-ordering easier, I've also moved the previous insights
chart into a legacy file and set up a proxy component that handles
switching based on the flag.
Next step is separating the filters.
