refactor!: unify apis with method, path order

[pi0]

Since the introduction of native method support for rou3, it feels much more ergonomic to have method, path in utils order also to make sure users won't miss method or mistakenly use it in reverse order. (this is a breaking change but since rou3 is barely adopted, should go well!)
