fix(gro-56): guard dev login page behind import.meta.env.DEV

The DevLoginSelector page (including the "Continue as default dev user"
button) was rendering in production when AUTH_DISABLED=true. This guards
the /login route so the page only renders in Vite development mode
(import.meta.env.DEV). Also removes the skip-login button entirely since
it bypassed user selection without any identity assertion.

- Guard /login route with import.meta.env.DEV in App.tsx
- Remove skipLogin button from DevLoginSelector.tsx
- Add vite/client types to web tsconfig
- Remove corresponding e2e test
