dev.knotless.uploadImage

Uploads the body, a PNG, JPEG, WebP or GIF, as a blob of the account logged in to this appview's web pages, as `knotless issue create --image` does: one over 1,000,000 bytes is drawn again as a JPEG that fits, at most 2000 pixels on its longest side. Its PDS keeps it only once a record attaches it: give it as one of dev.knotless.createIssue's, createPull's, createComment's or editItem's `images`, with a body linking to `url`. Requires the session cookie the pages' login sets.
