[Enhancement]: Support for Path-Style S3 Addressing

[VoigtSebastian]

What features would you like to see added?

The current S3 integration in LibreChat only supports virtual-host–style addressing.
However, some object storage providers do not support virtual-host–style addressing.
As a result, users who rely on these providers cannot use the integration as it stands.

More details

Proposed Solution

The AWS SDK for JavaScript already supports this via the s3ForcePathStyle configuration option.
By exposing this flag in LibreChat’s configuration, the integration could support both styles and remain compatible with a broader set of storage providers.

I believe this should only require changes in the s3 initialization with the aforementioned configuration flag.

Additional Notes

This should be a relatively small change.
I’m happy to contribute a PR if time allows (though I’m still new to TS/JS development).
If someone more experienced wants to take it on, that would be fantastic too.

fyi: I'm working on it. It is more work than initially assumed because the URL parsing to download from S3 breaks with path-style addressing. But still nothing mayor.

Hi @danny-avila,
since this issue was relatively important to me, I went ahead and fixed it by building a local version.
I know it’s not part of your current backlog, but if you’d like to include the changes, you can review them in my fork.
If you’re ok with them, I’d be happy to create a pull request and update the documentation with the new (optional) environment variable.
I wrote the code to minimize changes to the existing logic as much as possible.

Best regards, and thank you for maintaining such a well‑run open source project!

+1, for my setup I also need the path style.
@VoigtSebastian, could you create a PR for the changes you've made?

I haven't received any feedback yet, but yes I can open a PR. Maybe that will start a discussion 😄
