- Updated README to include KodBox in project vision. - Added model descriptions for clarity in Download, File, Folder, Group, Node, Order, Policy, Redeem, Report, Request, Response, Setting, Share, SourceLink, StoragePack, Tag, Task, User, and WebDAV. - Changed optional fields from Optional[...] to the new union type syntax (e.g., str | None). - Improved foreign key references in models for consistency. - Refactored relationships in models to use singular forms where appropriate. - Updated login service to reflect changes in request model types.
