Joe Li ca9eeec59d feat(embedded-e2e): add Playwright E2E tests for embedded dashboards ...

Adds five tests covering the embedded dashboard flow against the
world_health example: render, hideTitle UI config, chart rendering,
allowed_domains referrer check, and guest-token data access. Includes:

- A chromium-embedded Playwright project, excluded from the main
  project via testIgnore so it can be opted into separately.
- An EmbeddedPage page object and API helpers for embedding/guest
  tokens plus dashboard lookup by slug.
- A static test app (embedded-app/index.html) loaded from a minimal
  Node static server. Playwright bridges the guest-token fetch from
  Node into the browser via page.exposeFunction.
- EMBEDDED timeout/config constants.

Workflow integration and test-environment configuration land in a
follow-up commit.
