feat: Qobuz auth-token (user_id + token) login as a reliable alternative to email/password

Qobuz's email/password API login returns 401 even with valid credentials
(a known Qobuz limitation, unaffected by streamrip version). Add settings
fields for a Qobuz user ID + auth token (token stored encrypted); when both
are present StreamripClient uses use_auth_token=True, else falls back to
email/password.
