Move metadata.jsonl into images/ so ImageFolder picks up metadata

ImageFolder only loads metadata.jsonl from within the data_files
directory tree. With metadata.jsonl at root and data_files pointing
to images/**, the metadata was ignored (all columns null except image).

Now metadata.jsonl lives alongside the images in images/, with
file_name paths relative to that directory (e.g. "NEET_2024_T3/...").
