Describe the Bug
Setting the PROXY_SERVER environment variable appears to have no effect.

To Reproduce
Steps to reproduce the issue:

1. Set the PROXY_SERVER environment variable with a valid proxy server URL in the .env file (I'm using http://192.168.0.2:8080 which is the VPN gateway)
2. Run docker compose up -d
3. Scrape https://myip.com
4. Check the IP address returned in the response (e.g., in markdown or HTML)

Hmm, I'm skeptical that this is true since I believe it to be working for us in prod at Trieve, but not sure. It could have just been broken this whole time. Hopefully I can look at this in more depth at some point soon'ish.
