Update the Grafana board https://grafana.wikimedia.org/d/000000346/mediawiki-twocolconflict to be ready for monitoring when Two-Column-Edit-Conflict-Merge goes default. Most important:
- What percentage of resolved conflicts were fixed through the new interface?
- Ideally: What was the percentage per edit count basket.
- Some of the graphs contain a FIXME: check if we still need them and fix them or remove them from the dashboard.
- Rename the core / "default" workflow panels to "legacy"
- Averages should not include null (missing) data points, for example when some groups haven't experienced any conflicts.
Possibly use the numbers from https://grafana.wikimedia.org/d/000000213/mediawiki-edit-conflicts.
