feat(insights): look for level shifts in thirteen vitals over 180 days

The health-status read scanned five vitals over 90 days for a dated,
sustained level shift. It now scans every vital with a stable daily level
(adding RMSSD, diastolic pressure, pulse, body fat, respiratory rate,
oxygen saturation, walking heart rate and VO2 max) over 180 days, reads one
value per day per metric, leaves a metric unread when its module is off,
and reports how many days stand on each side of the break. The Coach keeps
its five-metric, 90-day scan unchanged.
