Etapp 1: kroppsdata synkas mot servern + BMR + dagens kcal-mätare på Hem

- Profile/myProfile med heightCm/birthYear/sex (fallback mot äldre server),
  updateProfile-mutation i GymApi
- Kroppsdata sparas lokalt och synkas: serverns värden vinner, lokala pushas
  upp om servern är tom (migrerar vågens lokala data)
- Mifflin–St Jeor-BMR (data/Bmr.kt)
- Hemskärm: Dagens kalorier-kort — aktivt loggat (dagens pass), telefonen
  (platshållare för etapp 5) och passivt (BMR-andel av dygnet, tickar per
  minut). Uppmaning om kroppsdata saknas.
- Version 0.5.0
