Pull request overview

This PR fixes the logout/unauthenticated flow in Console v5 so users are redirected to the in-app /login route (instead of Auth0 hosted https://auth.qovery.com/login) and preserves the intended post-login destination.

Changes:

• Redirect unauthenticated access under /_authenticated to the Console /login route with a redirect query param.
• Extend shared authLogin to accept an optional returnTo and pass it via Auth0 appState.
• Forward the redirect search param from the login route into authLogin so Auth0 can restore navigation after login.
