SSO: Auto redirect to SSO login when SSO_ONLY

[cwchristerw]

It would be nice to have a feature that will redirect you to SSO login automatically, when you have enabled SSO_ONLY.

Alternatively at least hide email field (or make it optional). Value is not used, because email is used from email that SSO provides. This might be related to #6191

It's already optional if you bookmark e.g. https://your.domain/#/sso?identifier=login as explained in #6191 (comment)

For the identifier you should use either the dummy one VW_DUMMY_IDENTIFIER_FOR_OIDC or an organization uuid.
