Subject: [PATCH] feat(pitch-deck): live-computed sum rows in Finanzplan (like
 Excel formulas)

Sum rows (is_sum_row=true) are now computed live in the frontend from
their detail rows, not read from stale DB values. This means:
- Category sums (Versicherungen, Marketing, Sonstige etc.) always match
- "Summe sonstige" = all non-personal, non-AfA rows
- "SUMME Betriebliche" = all rows including personal + AfA
- No more manual recompute needed after DB changes

Also: chart labels increased from 7-8px to 11px for readability.
