[bug] v2 dashboard: the old /apps/<app>/setup link freezes the tab

[EugenEistrach]

Executor version

2.0.0-beta.8 (built from the executor@2.0.0-beta.8 tag with a small server-side patch; the web app is unmodified). The setup route and AccountSelectionPage are unchanged on v2 at ed608b7.

How do you run Executor?

Self-host (Docker)

Operating system

Linux (Chrome)

What happened

Opening /org/<org>/apps/<app>/setup, with or without ?profile=, never leaves the page. The main area stays empty, the tab stops responding, and eventually Chrome shows "Aw, Snap!" (SIGILL). It happens for every app we tried; every other dashboard page works.

AccountSelectionPage (apps/hosted/web/src/implementation/pages/account-selection.tsx) renders <Navigate params={{…}} search={{…}} replace /> with new objects on every render. TanStack Router's Navigate (1.170.41) calls navigate(props) in a layout effect whenever props changes. The navigation re-renders the setup route before it commits, which creates new props and starts the next navigation, so it never completes. Pausing the frozen tab shows Navigate's effect → router.navigate → commitLocation → load, over and over.

What you expected

One redirect to /org/<org>/apps/<app>?view=accounts, which works when opened directly.

Steps to reproduce

1. Sign in to the dashboard.
2. Open https://<host>/org/<org>/apps/<any app id>/setup.
3. The tab stops responding within a few seconds.

Redirecting in the route's beforeLoad (throw redirect(...)) instead of rendering <Navigate> would likely avoid it.

Diagnostics / logs

Nothing on the server; the loop runs in the browser.
