Screen Time

Using the [screen_time_api_ios](https://pub.dev/packages/screen_time_api_ios) we should be able to capture screen time on iOS.

This is, however, a highly sensitive API access on iOS and it will be difficult to get such an app approved by Apple. Hence, care should be take to add this in a way, so it is easy to avoid more generally in CAMS. Potentially as a sampling package.

Start by reviewing the screen_time_api_ios package and the linked Apple documentation and WWDC session to understand the available access and approval constraints. Then identify how a sampling package would fit into CAMS and define the exclusion path; done means screen-time capture is isolated so it can be omitted from general apps.
