Email reminders to attend, log, and make meetings recurring

[nicholaschiang]

Current QuaranTunes setup:

"for us the way it usually works is parents book the first lesson, the teacher asks them if they would like it to be recurring, and if the parent says yes they decide whether or not to keep that same time and then the teacher goes onto picktime & changes the lesson status to recurring so it automatically goes onto their calendar for that time every week"
— Julia Segal (CEO of QuaranTunes)

We should send a reminder email to the parent/volunteer to make their meetings recurring. That email should simply have a CTA button that'll automatically make it recurring (showing the meeting open in a loading state in their calendar page).

We should trigger that email after the meeting has occurred.
