fix: change redirect url gitlab authorization

[paulorwd]

In production I was using using local url in gitlab authentication.

I need to take a look at this because if it makes sense, we need to make the change in the getAPIUrl() function instead to be changed in all places.

I agree, the ideal is to have a function with this responsibility. However, as I saw that it was already being worked on in other pages, I preferred not to rewrite much because I did not master complementing the Coolify structure.

Thanks for the PR. 💜️
I would like to concentrate on v4. That is why I do not plan to add more features to v3.
