test: update cognify test assertions to include chunks_per_batch parameter

Update all cognify test assertions to expect the chunks_per_batch=None
parameter that was added to the CLI command. This fixes three failing tests:
- test_execute_basic_cognify
- test_cognify_invalid_chunk_size
- test_cognify_nonexistent_ontology_file
