Yee 27c8b1a061 fix(nginx): use 127.0.0.1 in python conf to avoid ~1s IPv6 fallback latency (#17909)
## Problem

In the default deployment (`API_PROXY_SCHEME=python`), the nginx config
generated from `docker/nginx/ragflow.conf.python` uses:

```nginx
proxy_pass http://localhost:9381;  # admin
proxy_pass http://localhost:9380;  # api
```

Inside the RAGFlow container, `/etc/hosts` maps `localhost` to both
`127.0.0.1` and `::1`:

```
127.0.0.1   localhost
::1         localhost ip6-localhost ip6-loopback
```

But the backend services (`ragflow_server.py` on 9380, admin server on
9381) only listen on IPv4 (`127.0.0.1`). When nginx resolves `localhost`
to `::1`, the upstream connection fails and nginx falls back to the IPv4
address - each fallback adds ~1 second of latency.
