feat(assets): add ModelInfoPanel for asset browser right panel (#8090)

## Summary

Adds an editable Model Info Panel to show and modify asset details in
the asset browser.

## Changes

- Add `ModelInfoPanel` component with editable display name,
description, model type, base models, and tags
- Add `updateAssetMetadata` action in `assetsStore` with optimistic
cache updates
- Add shadcn-vue `Select` components with design system styling
- Add utility functions in `assetMetadataUtils` for extracting model
metadata
- Convert `BaseModalLayout` right panel state to `defineModel` pattern
- Add slide-in animation and collapse button for right panel
- Add `class` prop to `PropertiesAccordionItem` for custom styling
- Fix keyboard handling: Escape in TagsInput/TextArea doesn't close
parent modal

## Testing

- Unit tests for `ModelInfoPanel` component
- Unit tests for `assetMetadataUtils` functions
