test: enhance cache call assertions in crew tests

* Improved the test for cache hitting between agents by filtering mock calls to ensure they include the expected 'tool' and 'input' keywords.
* Added assertions to verify the number of cache calls and their expected arguments, enhancing the reliability of the test.
* Cleaned up whitespace and improved readability in various test cases for better maintainability.
