Attachment: Medium Rectangle ads in Nightly vs correct display

New Tab on Nightly 134.0a1 (2024-10-30) passes images fetched from Unified Ads API through the Pocket Image Proxy. That is, the image URL https://ads-img.mozilla.org/v/images?image_data=foo is turned into https://img-getpocket.cdn.mozilla.net/296x148/filters:format(jpeg):quality(60):no_upscale():strip_exif()/https%3A%2F%2Fads-img.mozilla.org%2Fv1%2Fimages%3Fimage_data%3Dfoo before fetching.

While this is unnecessary for all images served by Unified Ads API (Unified API already anonymizes user requests), it has the additional undesired effect of cropping images for Medium Rectangle ads. See attached screenshot for how medium rectangle ads are currentlu displayed in New Tab vs how they should be displayed.
