Incorrect typing for refresh token.

[proofit404]

Let say we have code block like this:

def create_token(profile_id: ProfileId) -> Token:
    user = User.objects.get(profiletable=profile_id)
    refresh = RefreshToken.for_user(user)
    return str(refresh.access_token)

That would produce error in mypy:

venv/lib/python3.12/site-packages/web/repositories/token.py: note: In function "create_token":
venv/lib/python3.12/site-packages/web/repositories/token.py:13:16: error: "Token" has no attribute "access_token" 
[attr-defined]
        return str(refresh.access_token)
                   ^~~~~~~~~~~~~~~~~~~~

Token.for_user class method returns cls() which allows subclasses returns it's own instances. But annotations says it would always be a Token.

Maybe typing.Self would work?

This should be resolved after #776 (not released yet) - please try the master branch version to confirm.

And duplicates #794.
