fix(download): retrieve full folder to resolve type error

Retrieve the full Folder object from FoldersApi instead of using the
FolderSimple returned by find_sub_folder when resolving DOI subfolders.
This fixes a type checker error under the upgraded pyright, and avoids
a potential AttributeError at runtime due to FolderSimple lacking the
path attribute.

Also upgrade dependencies and bump version to 1.3.16 in pyproject.toml.
