fix(pitch-deck): version-aware financial model + layout fix + COMPLAI spelling

Critical fix: All financial slides now use the version's preferred scenario
instead of always defaulting to Base Case (1M). This ensures the
Wandeldarlehen version shows its own lean financial plan.

- useFinancialModel: add preferredScenarioId parameter
- PitchDeck: extract default scenario from previewData.fm_scenarios
- Pass preferredScenarioId to all 5 financial slides
- FinancialsSlide layout: remove empty right column, full-width charts
- Remove ScenarioSwitcher + unused slider from FinancialsSlide
- Fix COMPLEI → COMPLAI in presenter script (only TTS pronunciation differs)
