Add models for guidelines, incidents, plot points, issues, acts, and world data

- Introduced new models: `GuideLine`, `Incident`, `PlotPoint`, `Issue`, `Act`, and `World` for managing book-related entities.
- Integrated encryption/decryption for sensitive properties in all models using user-specific keys.
- Added methods for CRUD operations and synchronization workflows with error handling and multilingual support.
- Improved maintainability with JSDoc comments and streamlined queries.
