Moving from Turtlelytics

TurtleReport was previously called Turtlelytics.

1. Install and activate TurtleReport first.
2. On activation it switches Turtlelytics off and moves everything over on each site: settings, sites, Google connections, schedules, recipients, delivery history, viewer access and display preferences.
3. Then delete Turtlelytics.

Saved secrets stay readable, the OAuth redirect URI already registered in Google Cloud keeps working, and secure report links you already sent stay valid until they expire.
