austinpower1258 b5fb304af0 Handle headless CI runners in browser find focus UI test
On WarpBuild runners without a GUI session, XCUIApplication.launch()
blocks ~60s then fails with "Failed to activate application (current
state: Running Background)". Wrap launch() in XCTExpectFailure so the
test can continue — keyboard and element APIs work via accessibility
even when the app is in .runningBackground.

Increase test execution time allowance from 120s to 180s to account
for the 60s activation timeout on headless runners.
