Surface the diffusion training API in the Images page. A "Train LoRA" button in the top
bar opens a self-contained dialog to fine-tune an SDXL LoRA on a folder of images: pick
the base model, dataset folder, output folder, an optional instance prompt, and the core
hyperparameters (steps, rank, resolution, batch, learning rate), then Start. The dialog
polls the training status while open and shows a progress bar, step count, live loss, and
the saved adapter path, with a Stop button for a clean stop.
The dialog is independent of the loaded generation model (training runs in its own
subprocess), and prefills the base model with the loaded checkpoint when it is SDXL, else
the SDXL base. api.ts gains startDiffusionTraining / stopDiffusionTraining /
getDiffusionTrainingStatus plus their types, matching the /api/train/diffusion routes.
