fix: rename server package from praxis-proxy-server to praxis

[nerdalert]

Resolving the build package name resulting in which failed with package(s) 'praxis' not found in workspace. Taking a guess the package is intended to be praxis since all of the docs/example configs reference it. Swapped it to praxis to get cargo run -p xxx working.

I went the path of least resistance with the name and files to touch 5 vs. 50. If you want it named praxis-proxy-server just say!

Ty!
