Dariton4000 7cc8beb2e6 Studio: add VLM image-size control for training
Studio vision fine-tuning had no explicit way to cap image resolution, so
  users could not trade visual detail against context and memory use from the
  training UI, YAML config, or API payload. :) Add a nullable `vision_image_size`
  setting that keeps the current model default when unset and applies a
  max-side resize when provided.

  - Add `vision_image_size` to the training request model, route payload, backend
    training config, and frontend API/types plumbing.
  - Validate the value server-side as either null or an integer in the supported
    256-2048 range.
  - Surface an Image Size selector for vision LoRA training with Default plus
    common preset sizes.
  - Include the value in training start payloads only for image-dataset vision
    models, and serialize it into vision-aware YAML configs.
  - Map backend model defaults back into the training store and reset the value
    when reapplying model defaults.
  - Pass the resize through the Torch trainer via `UnslothVisionDataCollator`
    using max-dimension semantics.
  - Apply the same max-dimension resize in the MLX VLM path before mlx-vlm's
    internal collation, preserving aspect ratio and avoiding upscaling.
  - Add backend validation coverage and MLX resize-size tests for the new
    behavior.
