Subject: [PATCH] Train LoRA dialog: stop suggesting absolute paths the backend
 rejects

The dataset and output placeholders showed /path/to/... examples, but the
training routes resolve those fields inside the Studio home and reject
absolute paths outside the approved roots, so following the placeholder
produced a 400. Use folder-name placeholders and say in the labels and the
dialog description where each folder resolves.
