- add utils/session.ts: on 401 clear auth state and redirect to SSO or /login with return path; singleton promise prevents duplicate redirects; typed AuthenticationRequiredError for callers
- add api/authRequest.ts: shared generic authRequest with token injection, response parsing and 401 hook
- migrate businessLine/containerService/delivery/machine/subsystemAuth/taskLog api modules to the shared helper, removing six duplicated implementations; keep getToken only for EventSource query-param auth
- Catalog: silence session-expiry error in instance-name precheck; prefer mysql delivery target by exact template name (matches backend DELIVERY_MYSQL_TEMPLATE_NAME default)
