- Add  `String? routeName` to the following context Navigation methods:
`to`, `off`, `offAll`. To enforce the usage of `RouteSettings` and avoid issues with GetxController not being disposed properly, and also to keep control and consistency in the methods.
- modified `RouterReportManager.reportRouteDispose` to make it work with context Routes.
- added extension_navigator.dart `_cleanRouteName` to remove unwanted format where the Route name is taking from the page Type in context Routes.
- added `GetStringUtils.paramCase` to support potentially a clean url name for the context Routes. So `/()=> MyView` can become `/my-view'
- added `GetUtils.snakeCase` and `GetUtils.paramCase` to support `_cleanRouteName` url Strings (currently deactivated.) Base code taken from the ReCase package and proper credit attributed in comments.

- Split dashboard and home routes (in example_nav2)
- Removed 'Pages in a router outlet shouldn't participate in the root navigator' restriction
