Lifts loginAsUserToken + pageWithUserToken out of members.spec.ts into
fixtures/role-page.ts (third file that needs them). Adds shadowing
coverage: viewer member sees no New-app / Add-domain / Settings / Save
/ +Add-route, editor sees Save but no Delete header, and CodeMirror
renders contenteditable=false for viewers.
