fix(apps): eliminate blank-app window on launch and add crash visibility

- start the apps server before createWindow instead of after the full
  service-init chain: the Apps view was reachable ~10s before port 3210
  was listening, so every app iframe opened to connection-refused
- retry EADDRINUSE binds (quick relaunch races left the server disabled
  for the whole session with no retry)
- app frame: auto-retry the iframe instead of a dead manual Retry, and
  surface when the apps server itself is down (new apps:serverStatus)
- log render-process-gone/child-process-gone reasons; renderer helper
  crashes were previously invisible in packaged builds
