Summary

Fixes a Playwright flake where a test times out in beforeEach while waiting for the app to start, e.g. add-layer-window.spec.ts › "expanding Russia folder shows Country entry" on #307 and a add-layer-window test in the #303 merge queue run. In both cases the test failed on its retry too.

The appPage fixture's setup time counted against each test's default 30 s timeout. In CI, startup is slow because the page's main thread is saturated while three workers run in parallel. In the #307 report, every trivial page.evaluate took 0.5–1 s. Timings from that report:

• Fixture setup: median 13.7 s
• Before hooks: up to 35 s, even in a run where every test passed

Tests with longer bodies already have test.setTimeout(60000). Tests with short bodies, like the add-layer-window ones, had no headroom.

Changes

• appPage now has its own fixture timeout of 120 s, so startup no longer counts against the test's timeout.
• The wait for the ready title is raised from 30 s to 60 s, now that it isn't limited by the test timeout.
• CI uploads www/test-results/ as playwright-test-results when the first Playwright run fails. Today the --update-snapshots re-run clears that directory, so the retry traces of the original failure were lost.

Testing

• Checked the timeout behavior with a standalone spec that has a 35 s fixture. With the shared timeout, it fails with the same "Test timeout of 30000ms exceeded" error CI showed. With its own timeout, it passes, including when followed by a beforeEach.
• CI=1 npx playwright test add-layer-window smoke passes locally (14/14).
