- Updated the FalukantCharacter model to include a default scope that excludes pregnancy-related fields for compatibility with older databases.
- Implemented a new method in FalukantService to conditionally retrieve pregnancy information based on database schema.
- Enhanced the FamilyView component to display a summary navigation for family relationships, including partners, children, and lovers.
- Updated internationalization files to include new translations for family-related terms and summaries.
