fix(pitch-print): cover layout, Finanzplan data source, target_date

Three critical fixes after reviewing the rendered PDF:

Cover (was: indigo block collapsed to top, white content stacked below):
- The .print-page class in print.css forces flex-direction: column !important,
  which broke the horizontal split. Wrap the cover content in a single grid
  container — the column-flex parent then has only one child so direction is
  irrelevant. Indigo block now runs full-height on the left.
- Title reduced 88pt -> 60pt so "BreakPilot ComplAI." fits without wrapping.
- Funding amount formatter now handles sub-€1M cases (€200k vs €0.2M).

Finanzplan (was: "nicht verfügbar" on both pages 20-21):
- page.tsx was querying the legacy pitch_fm_results table which isn't populated
  by the current pipeline. The interactive deck reads from fp_* tables.
- Wire in lib/finanzplan/adapter.ts (finanzplanToFMResults) which bridges the
  live fp_* tables to FMResult[] — same source the interactive deck uses.
- Fall back to live default fp_scenario if the version snapshot's fm_scenarios
  is empty.
- adapter.ts: populate total_customers + new_customers from fp_kunden_summary
  (was hardcoded 0).

The Ask:
- target_date was rendering as raw ISO timestamp "2026-08-01T00:00:00.000Z";
  now formatted as "Aug 2026" (locale-aware).
- Hero funding amount uses same sub-€1M formatter.
