Deps: delete reqwest as dependency

[tipogi]

The only usage of this dependency in the src folder is here. We should consider refactoring to remove it from production code and move it to dev-dependencies instead, reducing unnecessary dependencies in the final build.

Another option would be to use the url crate, which is a lightweight alternative. Additionally, reqwest::Url is just a re-export of url::Url, so using url::Url directly avoids pulling in reqwest as a dependency.
