This task involves the work of augmenting the dashboard to include information about what types of Edit Checks/Suggestions people being shown and how frequently people are seeing each.

Just to note, that's what the dashboard currently shows.

What it doesn't show is All VE edit sessions in which ≥1 Suggestion was available. The logging for that is what we added in T409206.

EDIT: I have decided I'm uncertain of what the meaning of "seen" is in this ticket, and have asked elsewhere for clarification.

To sum up, in this ticket's description:

• "available" means what's currently called "shown" in all our logging -- a check/suggestion has triggered and it is available for display in the sidebar/gutter/drawer, but it may or may not ever have actually been in the user's browser viewport"
• "shown" means the action's widget has actually been visible inside the user's browser viewport.

There's a bunch of questions about exactly what this means in the add-the-instrumentation child-ticket: T412334#11555575

Dashboard is updated to include this data in both the VEFU daily sessions with suggestions and VEFU daily sessions with checks charts. It's going to be undercounting the ones that're shown compared to the ones that're seen until the backport for T417452 goes out and starts giving us data, but that'll be in 20 minutes or so.
