- training-section.tsx: handleSaveConfig now passes
isVisionModel && isDatasetImage === true to serializeConfigToYaml,
matching buildTrainingStartPayload. Stops vision_image_size from
leaking into exported YAML for text-only datasets where the API
would have sent null.
- params-section.tsx: add 256 to visionImageSizePresets so the
dropdown spans the validator's full [256, 2048] range. Also render
a synthetic SelectItem for the current value when it was loaded
from YAML or model defaults and is not in the preset list, so the
controlled Select always shows the active size.
