Fixed dependency typos and conflicts

Fixed dependency typos and conflicts. One of the langchain libs will pull the appropriate version of openai lib, so comment out the openai line because. Otherwise, version conflict will result.

I've diagnosed the issue. It looks like a combination of two things:

1. The April container crashed with a Segmentation Fault (Exit 139), likely due to the aggressive 128k context window on the 31B model pushing the 24GB VRAM limit.
2. Several of the new *-llama services (including April) were missing their network aliases in docker-compose.yml, which caused the "Name or service not known" error when they weren't resolvable by other services.

I've posted an implementation plan to fix the aliases and restore connectivity. Should I also try reducing the context window slightly (e.g., to 96k) to stabilize the 31B model on that GPU?
