Dioxus websocket request doesn't include `base_path`

**Problem**

I set **base_path** to "my_app" for an Dioxus app behind a **Nginx** reverse-proxy.

Accessing `http://127.0.0.1/my_app/` produce two errors:

1. A panic caused by an `unwrap()` in [`fullstack/src/client.rs:51`](https://github.com/DioxusLabs/dioxus/blob/v0.7.1/packages/fullstack/src/client.rs#L51). This is clearly related to https://github.com/DioxusLabs/dioxus/issues/5032. I still provide the full error message below.

Collapsed error message

```js

2. The second issue is a websocket request on `ws://127.0.0.1/_dioxus?build_id=0` _(404)_ instead of `ws://127.0.0.1/my_app/_dioxus?build_id=0` _(200)_

**Steps To Reproduce**

1. **Dioxus.toml**

```yml
[application]

[web.app]

# HTML title tag content
title = "MyApp"

base_path = "my_app"

# include `assets` in web platform
[web.resource]

# Additional CSS style files
style = []

# Additional JavaScript files
script = []

[web.resource.dev]

# Javascript code file
# serve: [dev-server] only
script = []
```

2. **Minimal nginx configuration**

```nginx
events {}

http {
server {
listen 80;
server_name 127.0.0.1;

location /my_app {
# Proxy to Dioxus dev server (default: 127.0.0.1:8080)
proxy_pass http://127.0.0.1:8080;

proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
}
```

Steps to reproduce the behavior:

- `dx serve --web --port 8080 --addr 0.0.0.0`
- Open browser on `http://127.0.0.1/my_app` and inspect network requests. A GET on `ws://127.0.0.1/_dioxus?build_id=0` should appear.

- Test with `wscat`:

```bash
~$ wscat -c "ws://127.0.0.1/_dioxus"
error: Unexpected server response: 404
```

expected:

```bash
~$ wscat -c "ws://127.0.0.1/my_app/_dioxus"
Connected (press CTRL+C to quit)
Disconnected (code: 1006, reason: "")
```

**Environment:**

- Dioxus version: 0.7.6
- Rust version: 1.94.1
- OS info: Fedora Linux 43 (7.0.9-105.fc43.x86_64)
- App platform: web (fullstack)

**Questionnaire**

First issue is clearly related to https://github.com/DioxusLabs/dioxus/issues/5032

Second one I don't know if it is misconfiguration of my Dioxus app, my Nginx configuration or an issue in Dioxus itself that doesn't append `base_path` to its websocket calls.
