Multiple customer SSO configurations per Workspace

Allow a Featurebase Workspace to configure and manage multiple customer-facing SSO setups instead of relying on one global SSO login URL and JWT configuration.

This would support companies that have multiple products, brands, portals, or customer identity systems within one Workspace.

Each SSO setup should be able to have:

• Its own login URL and JWT verification configuration

• Routing rules that associate it with specific brands, custom domains, Messengers, Help Centers, or public portals

• Support for returning the customer to the correct surface after authentication

Featurebase should resolve the appropriate SSO setup from the active brand or domain while keeping the customer data and product configuration centrally managed in one Workspace.

This request concerns customer-facing SSO and is separate from Enterprise SSO used by teammates to access the Featurebase dashboard.
