* Remove Negroni in favor of the standard net/http server. * Remove gorilla/mux in favor of the standard net/http NewServeMux. * Remove gorilla/sessions in favor of Redis session_id cookie. * Remove the hacky glue controllers setup in favor of regular defined routes in the router.go file directly. * Update all Go dependencies for Go 1.24 * Move and centralize all the HTTP middlewares. * Add middlewares for Logging and Recovery to replace Negroni's.
