Feat/reduce duplication in fault condition (#26)
* refactor: create base fault condition class and mixin for common functionality * test: fix FC6 test and add cooling mode test case - Fix test_fc6_apply_with_fault to properly trigger fault in heating mode (OS1) - Add test_fc6_apply_with_fault_cooling_mode to test fault detection in cooling mode (OS4) - Ensure all test conditions meet FC6 requirements for both operating modes - All tests passing with proper assertions and documentation * test: add comprehensive test suite for AHU fault conditions - Add test files for FC1-FC10 with proper test cases - Fix FC6 test to properly trigger faults in both heating and cooling modes - Include initialization, error handling, and fault detection tests - All tests passing with proper assertions and documentation * style: apply Black hehe * Fix exception handling in _handle_errors decorator to properly handle MissingColumnError from different modules
