test: Bump goto timeout in flaky test_resource_management (#1916)

## Summary

- `tests/unit/browsers/test_browser_pool.py::test_resource_management`
has been failing intermittently on `windows-latest` + Python 3.14 with
`playwright._impl._errors.TimeoutError: Page.goto: Timeout 30000ms
exceeded`.
- Root cause: Playwright's default 30s navigation timeout is too short
for a cold Windows + 3.14 CI runner; the local test server is fine, but
Chromium's page load (waiting for `load`) overruns the default budget.
- Fix: Pass an explicit `timeout=60_000` to the single `page.goto(...)`
call in this test.
