refactor(cli): enhance grouping verification in `verifyReceiversGroup…

…ing`

- Improved the logic for matching actual groupings against expected ones by sorting both expected and actual groups before comparison.
- Added comments for clarity, ensuring that the purpose of each step in the verification process is well-documented.
- This update enhances the accuracy and readability of the receiver grouping verification process in the routing test command.
