feat(insights): unify range controls and part set across bespoke metric pages

Mount MetricRangeControls on the measurement-series bespoke pages (weight,
blood-pressure, pulse, bmi, sleep) so the range selector no longer vanishes
when navigating from a HealthKit metric. Mood, workouts, and medications are
event-driven rather than MeasurementType series, so they document the
omission inline.

Apply the canonical part set where the data supports it: blood-pressure and
sleep gain the diversity nudge + show-all-values foot link. Blood pressure
omits the single-series stat strip (it is sys+dia) and bmi omits the strip /
nudge / show-all entry (it is derived from WEIGHT), each with an inline note.
