Daniel Han af638f98c3 Diffusion LoRA training: harden config handling, cancellation, SDXL conditioning, and safety
Addresses review findings on the SDXL LoRA trainer:
- Gate the base model with the same trust check as inference (unsloth/*, allowlisted
  official bases, or a local path) before from_pretrained, so an untrusted remote repo
  is never fetched or deserialised.
- Check the stop signal before the (slow) model load, not only between steps, so a
  cancel during download is honoured; a stop may carry save=False to cancel without
  leaving a partial adapter.
- Per-sample SDXL add_time_ids from the actual crop (original size + crop offset, with
  the offset mirrored on horizontal flip) instead of a fixed uncropped-square tensor.
- Apply EXIF orientation before resize/crop so rotated photos train upright.
- Skip gradient clipping when max_grad_norm <= 0 (the Studio 'disable' value) instead
  of scaling every gradient to zero.
- Coerce Studio config strings/blanks: learning_rate string to float, blank hf_token to
  anonymous, gradient_checkpointing 'none'/'true'/'unsloth' to bool; reject a zero/negative
  lora_alpha or learning_rate.
- Alias the generic Studio training payload keys (model_name/max_steps/batch_size/lora_r/
  lr_scheduler_type/random_seed) onto the diffusion field names.
- Mirror the trained adapter into loras/diffusion so the Images LoRA picker discovers it.
- Report worker exceptions in both message and error keys so the failure is not lost.

Adds regression tests for the config coercion/validation and aliasing.
