Refactor Request: Improve Maintainability of Redundant Docker Compose (OpenAI)

[bijoy26]

Issue

IMHO, the docker-compose-openai.yaml (introduced in #32) is not easy to comprehend at one go. It repeats the same environment and build configurations across 12 services. This impacts readability, maintainability and updates (error-prone) to a high margin for lab maintainers & students.

Proposed Change

It can be refactored using Compose Fragments (YAML anchors and aliases) to centralize shared configuration into a single template, ensuring consistency across all lab instances. This should reduce the file size by ~70%.

Example:

x-chat-base: &chat-base
  build: ...
  environment: ...

services:
  chat-copilot-1:
    <<: *chat-base
    ports: ["127.0.0.1:4001:4000"]
    volumes: [...]

I'd be happy to file a PR to improve the maintainability of these labs.

Unlike docker-compose.yaml, I'm hoping this variant isn't py generated 🤞, unless the change needs to take place in the generator.

Mentioning @mart123p to take a look / assign right person when convenient. I'm not sure about the dedicated maintainer pool of this repo, so excuse my random ping if you're not the intended one.
