feat: update AutoLoopCalculatorTTSBatch to support multiple files

- Added `file_names` to INPUT_TYPES and `current_file_name` to RETURN_TYPES.
- Removed `INPUT_IS_LIST = True` to avoid double nesting in ComfyUI list processing.
- Cleaned up temp files (`test_loop_syntax.py`, test `.sh` scripts).
- Verified `BatchTextFileReader` does not exist in the repository.
