feat(vorsorge): widen the linkable measurement set to the body-comp family

The reminder type allow-list exposed 7 of the full MeasurementType enum.
Widen it to the ~15 active-measurement set: vitals (weight, BP, pulse,
glucose, SpO2, temperature) plus the body-composition family a scale
produces (fat mass, fat-free mass, muscle, lean body mass, bone mass,
body water, visceral fat, BMI). One step on the scale satisfies every
linked reminder at once. Passive scores, cumulative activity, and device
events stay excluded — nudging someone to 'go measure' a passive sample
makes no sense.

App-layer only: the column is the full enum, so no migration. Group the
dropdown (Vitals / Body composition) and add the labels across all six
locales.
