Transition from DEV network stats to XT.
When XT stats are available, transition to prefer them over DEV,
since they aren't subject to hardware driver bugs. Only switches at
the first atomic XT bucket, and adds a Settings.Secure flag to force
back to DEV if needed. Includes tests to cover transition.
Fix tests where device overlay would change which network types
reflected data usage. Test both history and summary APIs. Fixed
collection timestamps to reflect full buckets.
