📝 Walkthrough

Walkthrough

This PR updates Configure SSO end-to-end: many locale files now reference Single Sign-On (SSO) and simplify the select-provider localization shape; shared localization types were adjusted (selectProviderStep, testUrl action label, testResults.empty, provider-specific saml attributeMapping); UI changes include rehydrating provider selection, removing enterprise-connection creation from verify-domain, conditional mounting of select-provider, changing the permission key to org:sys_entconns:manage, refactoring ConfigureStep to provider-driven attribute mapping, adding an Open test URL flow and test-results empty state, instrumenting UI with elementDescriptor/elementId keys, and adding a primary-email-domain footer in the navbar. Tests were updated to reflect copy and permission-key changes.
