test(console): stabilize authenticated smoke contract

[StringKe]

Summary

• add a dedicated, non-sensitive authenticated Console smoke hook
• replace three waits on hidden account-menu email text with the stable hook
• retain semantic authentication assertions through /v1/me, active organization, manager assignment, session status, and platform API checks

Root cause

The product redesign intentionally moved the user email into the closed Account dropdown. The main browser smoke still waited for that email in document.body.innerText, so authentication and Console rendering succeeded but the presentation-dependent wait timed out.

Validation

• PASS node --check scripts/run-three-worker-browser-smoke.mjs
• PASS pnpm --filter @xid-kit/console test -- ConsoleLayout.test.tsx (29 files, 146 tests)
• PASS pnpm --filter @xid-kit/console check
• PASS pnpm --filter @xid-kit/console build
• PASS pnpm run test:web-routes (19 tests)
• PASS pnpm run security:secret-scan
• PASS git diff --check
• SKIP local browser run by explicit request; the authoritative main CI smoke will run after merge
