## Summary
Adds a dropdown filter to the model browser that allows users to filter
assets by ownership (All, My models, Public models), based on the
`is_immutable` property.
## Changes
- **Filter UI**: Added ownership dropdown in
[AssetFilterBar.vue](src/platform/assets/components/AssetFilterBar.vue#L30-L38)
that only appears when user has uploaded models
- **Filter Logic**: Implemented `filterByOwnership` function in
[useAssetBrowser.ts](src/platform/assets/composables/useAssetBrowser.ts#L38-L45)
to filter by `is_immutable` property
- **i18n**: Added translation strings for ownership filter options
- **Tests**: Added comprehensive tests for ownership filtering in both
composable and component test files
## Review Focus
- The ownership filter visibility logic correctly checks for mutable
assets (`!is_immutable`)
- Default filter value is 'all' to show all models initially
- Filter integrates cleanly with existing file format and base model
filters
