fix: remove type annotations, use HealthUnitPrefix + millimeterOfMercury

- Remove all TS type annotations (HealthQuantityType, HealthUnit etc.)
  to avoid 'string not assignable' errors — let the app infer types
- HealthMetricPrefix → HealthUnitPrefix (correct enum name per docs)
- HealthUnit.fromString('mmHg') → HealthUnit.millimeterOfMercury()
  (confirmed in docs: line 35229)
