Angular v19 prerender uses the wrong package.json

### Which @angular/* package(s) are the source of the bug?

ssr

### Is this a regression?

No

### Description

when running an angular app that uses `AngularNodeAppEngine` from "@angular/ssr/node" and `outputMode` set to `server` it reads `imports` from `src/package.json` which is set to be used in dist

package.json
```
"imports": {
"#configs/*": "./browser/configs/*.js"
}
```
in the source code the configs folder is live in "src/configs" but copied at build time into "dist/browser/configs"
the same goes for many dynamic imports that assume the app runs inside the dist dir, i.e. the paths may be differ from the corresponding paths in the source code.

The prerender should run the same way as the original app runs i.e. from dist.

another thing, I cannot find an option to totally disable the prerendering as `prerender: false` now has no effect

Bắt đầu với entry point AngularNodeAppEngine từ @angular/ssr/node và các import trong src/package.json được nêu trong báo cáo, sau đó theo dõi cách angular.json gọi server output và prerendering thông qua src/server.ts. Xác minh rằng việc phân giải diễn ra từ dist thay vì src, và rằng thiết lập prerender: false được ghi rõ trong tài liệu sẽ ngăn prerendering.
