create_text2music_ui() sorted the saved *_input_params.json files with
int(name.split('_')[1]), which assumes the generated
output_<timestamp>_<idx>_ shape. Output names are user-controlled — via
infer.py --output_path or a save_path from the UI — so any other name
raised ValueError while the Blocks were being built and took the whole
interface down before it could start:
ValueError: invalid literal for int() with base 10: 'base'
Sort by mtime instead. That is what "previous generated input params"
means anyway (newest first) and it works for any filename; a file that
disappears between listdir() and getmtime() sorts last rather than
raising.
