feat(falukant): add scandalExtraDailyPct field and update related components

- Introduced a new field `scandalExtraDailyPct` in the relationship state model to track additional scandal risk per day, with validation constraints.
- Updated the FalukantService to include the new field in relevant calculations and data handling.
- Enhanced the frontend components, including RevenueSection and FamilyView, to display the scandal risk information and updated price calculations.
- Added localization entries for the new field in multiple languages to ensure clarity for users.
