error handling of incorrect verification code

[DancingQuanta]

If the verification code is incorrect then an exception from click will occur in the backend.py.

Do you already have an API key for zotero-cli? [y/N]: n
Opening https://www.zotero.org/oauth/authorize?oauth_token=47cc66ba4789462517c6&notes_access=1&library_access=1&write_access=1&all_groups=read&name=zotero-cli in browser, please confirm.
Enter verification code: test

Thjs shows there needs to be a context passed to the backend eg ctx.

Also can I use local storage without API key?
