refactor: rewrite entire codebase in axum instead of actix

Replaces actix with axum for web, allows us to use socket.io and gives us access to the tower ecosystem of middleware

breaks compatibility with our current websocket implementation, needs to be reimplemented for socket.io

src/api/v1/invites/id.rs
