test(backend): add Playwright E2E suite + deps for editor basics, chat persistence and publish

- Covers 9 flows: title persistence through Hocuspocus reload, settings drawer, chat panel
open/close, new-conversation clear, stable user identity across reloads, publish round-trip
- Bundled as `npm run test:e2e` (opt-in, not part of the fast hermetic suite) with spec-driven
fixtures that spin up a real Express + Hocuspocus server on an ephemeral port
- Brings playwright + @playwright /test into backend/package.json
