- Implemented PDF generation for collections, allowing users to create printable itineraries. - Added support for Noto fonts to ensure proper rendering of text and emojis in PDFs. - Enhanced admin interfaces for achievements and adventures, improving usability and data management. - Introduced new fields and methods in models and serializers to support geolocation features and improve data handling. - Updated migrations to transition from latitude/longitude fields to a unified PointField for geographic data. - Added tests to validate PDF generation functionality and ensure reliability.
