Settings: promote Live Activity to top-level menu under Alert Management

Moved the 'Live activity' NavigationLink out of AlertManagementView and
into SettingsView's alertManagementSection, directly below the Alert
Management row. Both now share a Section using the LargeButton style.

The new Live Activity row uses 'rectangle.on.rectangle' as the icon and
the descriptive text 'Lock Screen, Dynamic Island, and CarPlay display'.

Rationale: Live Activity is an output/display concern, not an alert
permission concern, so users were unlikely to look for it inside Alert
Management. Surfacing it at the top level makes it discoverable.
