fix: disable inspect for non-previewable assets (#8989)

## Summary
Prevent text/other assets from opening a blank fullscreen viewer by
restricting inspect/zoom to previewable media kinds.

## Changes
- Add `isPreviewableMediaType` helper in shared `formatUtil`.
- Gate inspect/zoom actions in `AssetsSidebarTab`, `MediaAssetCard`, and
`MediaAssetContextMenu` using an allowlist (`image`, `video`, `audio`,
`3D`).
- Build gallery items from previewable assets only.
- Add unit tests for `isPreviewableMediaType`.

## Why
`ResultGallery` only renders image/video/audio; text/other assets could
previously enter fullscreen with no renderable content.

## Review Focus
- Verify text/other assets no longer show Inspect and do not open
fullscreen.
- Verify image/video/audio behavior is unchanged.
- Verify 3D still opens the 3D viewer dialog.
