Optionally allow:
* Numbers you have contacted
* Numbers within the selected groups (Toll-Free, Local)
* N registered call from the same number within T minutes
* Numbers from messages
* Numbers passing STIR verification (Android 11)

Contacted, Groups, Repeated, Messages options and the main toggle have additional settings. You can
open them by long click.
