feat: enhance report management and PDF generation capabilities

- Introduced new API endpoints for managing report definitions, including listing, creating, and updating reports.
- Updated the frontend to include a dedicated section for configuring reports, enhancing user navigation and experience.
- Modified existing components to link to the new report settings, ensuring seamless access to report functionalities.
- Improved the report catalog API to support multiple definitions per profile and added validation for report limits.
- Updated documentation and tests to reflect the new features and ensure proper functionality.
