Subject: [PATCH] fix: show setup UI when a restored Train view hides it on
 first run (fixes #4441)

The desktop restores the last-used view from localStorage synchronously at
startup. When that is Train, body.training is set and the stylesheet hides
async; when it resolves to setup-needed/failed, firstRun()/failWithSetup()
render the setup wizard or failure banner into #thread -- which is now hidden
behind the Train view. The title bar shows "setup needed" with nothing on
screen to act on: the reported Windows dead end.

Force the Chat view (showEngineGate) when the engine is not ready so the
deliberate Train choice returns once the engine is up. Engine and Rust
supervisor untouched.
