Remove TestConvertHessBook and TestDebugHess (both referenced a non-existent Hess EPUB at an absolute local path) and TestConvertCPByTextSearch (referenced a Crime and Punishment EPUB in the local uploads directory). These were development-time debug tests that only worked on the author's machine. All CFI/KEPUB conversion behavior is already covered by the proper fixture-based tests (TestKEPUBRoundTrip, TestKEPUBConvertKEPUBToStandard, TestKEPUBConvertWithEmElements, etc.) which use createTestEPUB and createTestKEPUB helpers.
