Subject: [PATCH] feat(pitch-deck): formula engine + tooltips for betriebliche
 Aufwendungen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Engine formulas added:
- Berufsgenossenschaft (F): 2.77% of total brutto payroll (VBG IT rate)
- Internet/Mobilfunk (F): Headcount × 50 EUR/Mon
- Allgemeine Marketingkosten (F): 10% of monthly revenue

UI: Hover tooltips on all (F) and computed rows showing the formula.
SUMME matcher updated for renamed "SUMME Betriebliche Aufwendungen".
