Enhance route naming system in Sanic mixins

Sanic mixins have been updated to support more informative route naming. `_generate_name()` is now enhanced to include methods and URIs as part of the route name, providing more context about the route configuration. The update also takes care of potential naming conflicts in different scenarios.
