Fixed cairo and gi module issue

[gitSouvik]

While deploying this bot to my Discord server, I ran into multiple runtime issues related to missing gi / cairo dependencies when running inside a Docker environment (especially with minimal base images).

These issues caused the bot to crash during startup due to incomplete system-level bindings required by PyGObject and Cairo.

I’m requesting that this PR be merged to prevent other users from running into the same deployment issues.

---

Changes Made

• Updated the Dockerfile to install required system dependencies for gi / cairo
• Updated pyproject.toml to ensure correct Python dependency resolution
• Improved Docker build reliability for production deployments (e.g. Railway)

After these changes:

• The bot starts successfully without import errors
• Cogs load correctly without gi / cairo failures
• The bot runs stably for long periods inside Docker containers

---

Note

• Tested in a clean Docker environment
• No functional behavior of the bot was changed outside of fixing deployment stability

Thanks for this bot. Its very useful. Working great in our college Discord community.

Weird, I thought this was already fixed with how we installed it. I don't really want dependencies here and that's why we moved it all to the Dockerfile.

Python is just terrible at handling dependencies.

[gitSouvik]

Yeah, Docker (was) still giving those errors. You can check it yourself if you don’t believe me.

About the .env file stuff — I had actually hosted the bot on a free platform and set the environment variables directly on that platform. Later, I forgot about that and assumed the variables were being read from the .env file (instead of .env.example), so I changed them here. (I was wrong — those variables were changed globally)

[gitSouvik]

@cheran-senthil Should I change change .env to .env.example and send and new PR ?

[algmyr]

I'm confused what the change you are talking about is. .env.example is an example, and .env is what is actually used. The instructions say to make a copy of the file and to update the needed values inside it.

[algmyr]

Why? We're not using cgi at all, are we?

[gitSouvik]

Sorry for the late reply — I was not well recently.
I reviewed the legacy-cgi information and realized that I had incorrectly used it as a workaround for the gi module error.

Removed

Also I was facing issue on those fonts. It was giving 403 error while requesting the NotoSansCJK-Bold.ttc and NotoSansCJK-Regular.ttc fonts, so added them manually.

Fixed separately in #539. Font issues will be fixed in #543.
