ng serve not working behind reverse proxy basehref/servepath

### Command

serve

### Is this a regression?

- [X] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

before vite

### Description

I provide remote training for Angular using VSCode in the browser.
It is no longer possible to use the vscode port forwarding to access the ng dev server as basehref and servepath combinations to not yield the correct result when @angular node resources are to be loaded. It works for all other assets/files in the project.

### Minimal Reproduction

Use code-server oder vscode server access through web browser.

ng new
ng serve --host 0.0.0.0 --disable-host-check

Open the forwarded port, URL becomes f.e.
https://student01.remote-training.de/proxy/4200/

### Anything else relevant?

I tried various configuration combinations using prebundle, basehref and servepath only to experience worse problems like beeing redirected to https://student01.remote-training.de/proxy/4200/proxy/4200/

Empieza reproduciendo la configuración reportada `ng serve --host 0.0.0.0 --disable-host-check` mediante la URL reenviada `/proxy/4200/`. Investiga cómo afectan las opciones `basehref` y `servepath` a las Angular node-resource URLs y a las redirecciones, incluido el caso de `/proxy/4200/` duplicado. Se considera completado cuando el servidor de desarrollo reenviado carga esos recursos sin una ruta incorrecta.
