[backport cloud/1.35] feat: Add HuggingFace model import support (#7730)

## Summary
Backport of #7540 to cloud/1.35 branch.

- Adds HuggingFace as a model import source alongside CivitAI
- Implements extensible import source handler pattern
- UTF-8 filename decoding for international characters
- Alphabetically sorted model types
- Feature flag `huggingfaceModelImportEnabled` for gradual rollout

## Conflict Resolution
- `src/platform/remoteConfig/types.ts`: Kept both target branch's stripe
fields and added PR's huggingface field
- `src/platform/assets/components/UploadModelFooter.vue`: Adapted
`Button` component to `IconTextButton`/`TextButton` as the new Button
component is not available in this branch

Original PR: #7540
