Team members who receive a project invitation email are taken to the identity server login page, where they must manually enter a subdomain before reaching their organization's identity provider. This adds a manual step for every new team member, even when a single sign-on configuration is already fully set up.

Suggested Enhancement: Allow the invitation email link to route directly to the configured identity provider (using the existing IdP-initiated sign-in mechanism) instead of the intermediate subdomain-entry page, at least for projects with only one active SSO configuration.

Customer Benefit: New team members reach their organization's login screen in one click instead of navigating an extra identification step, speeding up onboarding for large teams.
