Extract types, constants, helpers, and UI pieces (shared LoadingSkeleton/
EmptyState/StatusBadge/CopyButton, SSOConfigFormModal, DeleteConfirmModal,
ConnectionTestPanel, SSOConfigCard, SSOUsersTable, SSOInfoSection) into
_components/ and _types.ts to bring page.tsx from 1482 LOC to 339 LOC
(under the 500 hard cap). Behavior preserved.
