Luke Mino-Altherr ce4837a57c feat: display and upload Civitai preview images in model upload flow (#7274) ...

## Summary
Stores and displays base64-encoded preview images from Civitai during
the model upload flow, uploading the preview as a separate asset linked
to the model.

## Changes
- **Schema**: Added `preview_image` field to `AssetMetadata` schema
- **Service**: Added `uploadAssetFromBase64` method to convert base64
data to blob and upload via FormData
- **Upload Flow**: Modified wizard to first upload preview image as
asset, then link it to model via `preview_id`
- **UI**: Display 56x56px preview thumbnail alongside model filename in
confirmation and success steps

## Review Focus
- Base64 to blob conversion and FormData upload implementation
- Sequential upload flow (preview first, then model with preview_id
reference)
