Detailed Description

Regression tests for images surviving the .wxm serialization round-trip.

Copying cells to the clipboard is essentially the same code path as saving a .wxm worksheet (Format::TreeToWXM), so these tests guard both. The concrete bug that motivated them: ImgCell::GetCompressedImage() read the raw compressed buffer without waiting for a still-running background image load, so copying a freshly drag-dropped image serialized it as zero bytes -> a "cannot render the image / zero length" cell after paste. Here we build image cells in several formats, serialize them to .wxm and parse them back, and check the image data survives (byte-for-byte – .wxm stores the compressed bytes verbatim as base64). A file-loaded image additionally exercises the background-load path that GetCompressedImage() must wait for.
