fix: derive fp_scenario IDs from version snapshot, eliminate hardcoded UUIDs

The fm_scenarios array in each pitch version snapshot already stores the
fp_scenario IDs directly (same pattern 1 Mio used). Wandeldarlehen snapshots
were missing Bear/Bull entries — updated in DB to add them.

- /api/data: include fp_scenarios in version response (was omitted)
- PitchDeck: derive fpBaseScenarioId from data.fp_scenarios
- useFpKPIs: accept fpBaseScenarioId instead of isWandeldarlehen boolean
- AssumptionsSlide: find Bear/Base/Bull by name from fpScenarios prop
- FinanzplanSlide: initialize from fpBaseScenarioId, use version scenarios for selector
- FinancialsSlide / ExecutiveSummarySlide: pass fpBaseScenarioId to hook
- types: add FpScenarioRef + fp_scenarios field to PitchData

No UUID hardcoded in any component. Adding a new pitch version only
requires setting the correct fp_scenario IDs in its fm_scenarios snapshot.
