fix(ci): build before test and install Playwright browsers in pages workflow

[abbaseya]

Summary

The Updating Github pages workflow has been failing on every push to main since the Karma→Playwright migration (commit be7e235). Two issues, both fixed here:

1. Build runs after test, but the integration test requires the build output

packages/js-sdk/tests/integration/full-chain.spec.ts:5:

const SDK = require('../../lib/index');

lib/ is the rollup output produced by yarn build. The current order in Generating coverage and docs was yarn test then yarn build, so Playwright's test-file discovery crashed:

Error: Cannot find module '../../lib/index'
Require stack:
- .../packages/js-sdk/tests/integration/full-chain.spec.ts
- .../node_modules/playwright/lib/transform/transform.js

The crash happens before any browser even launches.

2. Playwright's bundled chromium was never installed

The workflow installs system google-chrome-stable (Karma-era leftover), but Playwright uses its own bundled chromium binary, not the system Chrome. Without playwright install, the browser tests would fail at browser-launch time even after fixing (1).

Why this didn't bite us in PRs

qa.yml already had both pieces in place: it runs yarn build before yarn test:mocha/yarn test:browser, and it runs yarn playwright install --with-deps chromium. So PR-time checks pass while pages.yml has been red on every merge.

This change brings pages.yml into alignment.

Note

The system google-chrome-stable install block is left untouched — it's now redundant with --with-deps doing the same thing via apt-get, but removing it is scope-creep cleanup that should be a separate PR.

Test plan

• After merge, the merge commit's auto-triggered Updating Github pages run on main completes successfully.
• Verify the gh-pages branch is updated with fresh docs/coverage.
