feat(pitch-deck): live-compute sums for Liquidität + Kunden + Umsatz tabs

Extended live-compute to ALL tabs:
- Liquidität: "Summe ERTRÄGE" = sum of einzahlung rows,
  "Summe AUSZAHLUNGEN" = sum of auszahlung rows
- Kunden: GESAMT rows = sum of tier detail rows
- Umsatz: GESAMTUMSATZ = sum of all revenue rows
- Materialaufwand: SUMME = sum of cost rows

ÜBERSCHUSS rows kept from DB (complex multi-step formula).
