Avsluta-överblick med redigerbar passtid + kcal-summering med uträkning

- Avsluta-dialogen visar övningar/set/reps/volym, passtiden går att justera
  (±1/±5 min, skickas som durationSecondsOverride — för alla gånger man
  glömt avsluta) och en kcal-uppskattning som räknas om live med tiden
- 'Hur räknas detta?' visar MET-formeln (MET × kroppsvikt × timmar) med
  siffrorna per övning; kroppsvikten cachas från profilen
- Passdetaljen i historiken: summeringskort (tid, set, volym, kcal) +
  samma förklaringsdialog med serverns faktiska fördelning, och kcal
  per övning på varje övningskort
- Room v2-migration för durationSecondsOverride
