fix(test): fix flaky adaptive playwright crawler timeout test

On slow Windows CI, Playwright browser startup exceeded the 10s relaxed
timeout, causing the browser fallback to fail. BasicCrawler then retried
the request, and the retry's static crawl succeeded (using the mutated
timeout), calling the static handler a second time.

Fix: increase relaxed timeout to 120s for slow CI, and set
max_request_retries=0 since the test validates fallback, not retries.
