## Summary
Fix "Open Image" on cloud opening a new tab that auto-downloads the
asset instead of displaying it inline.
## Changes
- **What**: Add `openFileInNewTab()` to `downloadUtil.ts` that fetches
cross-origin URLs as blobs before opening in a new tab, avoiding GCS
`Content-Disposition: attachment` redirects. Opens the blank tab
synchronously to preserve user-gesture activation (avoiding popup
blockers), then navigates to a blob URL once the fetch completes. Blob
URLs are revoked after 60s or immediately if the tab was closed. Update
both call sites (`useImageMenuOptions` and `litegraphService`) to use
the new function.
## Review Focus
- The synchronous `window.open('', '_blank')` before the async fetch is
intentional to preserve user-gesture context and avoid popup blockers.
- Blob URL revocation strategy: 60s timeout for successful opens,
immediate revoke if tab was closed, tab closed on fetch failure.
- Shared `fetchAsBlob()` helper is also used by the existing
`downloadViaBlobFetch`.
