Allow admins to sign out all active SSO users#854

Add a board-level action that lets admins revoke all active SSO sessions with a single click. Once signed out, users will need to authenticate again through the configured identity provider before accessing the board. This gives admins a self-service way to immediately enforce access changes after disabling SSO, rotating secrets, or removing users from their identity provider.

Still waiting on this feature to be implemented.

Any updates on this?
