wylovelyi 6b948fa675 fix(#787): make the image-preview title actually derive from the original URL ...

Verified against the bundled viewer.min.js: the `title(image, imageData)` callback
receives the <img> element Viewer.js creates internally (view(): `var image =
document.createElement('img')`), NOT the original <div>. Viewer only forwards the
attributes listed in `inheritedAttributes` (default: crossOrigin, decoding, isMap,
loading, referrerPolicy, sizes, srcset, useMap) when building that <img>, and
`data-original-url` is not in that list. So the previous title function always read
null and the title stayed 'image' -- the fix was a no-op at runtime.

Fix: add `data-original-url` to Viewer's `inheritedAttributes` so the original URL is
forwarded from the thumbnail <img> to the title <img>, letting
`getImageNameFromOriginalUrl` return the real filename (and not the CORS-proxy URL).

Also updates PictureFilePreviewTests to assert `inheritedAttributes` is configured
with data-original-url, locking the regression.
