Phasenkopf neu + Bezugsrate (Verzehrrate) beim Sonstigen Vermoegen
Deploy App / deploy (push) Successful in 1m2s
Details

Browse Source 
- Sonstiges Vermoegen bekommt "Jaehrliche Bezugsrate (Entnahme)": mindert das Vermoegen
  (gekappt am Bestand) und fliesst jaehrlich ins Cash.
- Phasenkopf neu strukturiert: Einkommen / Ausgaben / Quote, dann Geplante Sparrate
  (3a + Vermoegen-Sparbeitrag + Amortisation + Tilgung) und Geplante Verzehrrate
  (Bezugsraten), dann Kapitalzufluss (Verkaeufe + PK-/3a-Bezuege aus dem Uebergang) und
  Kapitalinvestitionen (Zusatz-/Neuinvestitionen + sofortige Tilgungen), dann Vermoegen.
  Die Cash-Zeile im Kopf entfaellt (die Cash-Zeile in der Matrix bleibt).
- Engine liefert plannedSaveRate/plannedWithdrawRate/capitalInflow/capitalInvest.
- Golden Tests: Bezugsrate ins Cash + Kapitalzufluss/-investitionen (10 gruen).
