[Bug]: Hardcoded mdi-v6 import in bootstrap-icons.js breaks Vite SSR with @quasar/extras v2 + Express redirect error

[bekaku]

What happened?

When running a Quasar Vite project in SSR mode with @quasar/extras v2.0.0, the dev server crashes with a Vite pre-transform error.

The issue occurs because quasar/icon-set/bootstrap-icons.js has a hardcoded import pointing to @quasar/extras/mdi-v6 (to borrow the subscript/superscript icons). Since @quasar/extras v2 dropped mdi-v6 in favor of mdi-v7, Vite fails to resolve this module.

Furthermore, when this Vite import analysis error occurs, the Quasar SSR dev webserver attempts to handle the error but incorrectly passes the file path as an HTTP status code to Express's res.redirect(), resulting in an ERR_HTTP_INVALID_STATUS_CODE crash, which masks the original Vite error.

What did you expect to happen?

1. The bootstrap-icons.js should not hardcode mdi-v6 (perhaps update it to mdi-v7 or conditionally resolve it) so it remains compatible with @quasar/extras v2.
2. The SSR error handler should correctly parse the Vite error without triggering an invalid status code in Express's res.redirect().

How to reproduce?

1. Create a Quasar project with @quasar/app-vit (v2.6.1) and quasar (v2.19.3).
2. Install @quasar/extras v2 (e.g., ^2.0.0).
3. Set the icon set to bootstrap-icons.
4. Run the dev server in SSR mode: pnpm dev -m ssr (or quasar dev -m ssr).
