fix(integrations): give Oura and WHOOP a 48 h silence window

Their rings and straps upload only when the phone app is opened, so a day
without opening it is ordinary and must not page the operator. Wearables
whose cloud receives data on its own keep 24 h, Apple Health keeps 48 h,
and scales, cuffs and Strava never alert on silence.
