fix(admin-web): auto-reload on stale dynamic-import chunks after deploy

Listen for vite:preloadError and router onError, force a one-shot reload
(10s cooldown via sessionStorage) when a hashed lazy-loaded module 404s
because a new deploy replaced it. Eliminates the user-visible "Failed to
fetch dynamically imported module" error on login and route navigation.
