Subject: [PATCH] feat: add a Files on this computer settings page to the
 desktop app

The settings nav test drew every page but recovery; the new page waits for the desktop app's sync engine like recovery waits for its probe, so the test leaves it out too and a new test checks it shows while the engine runs.
