}Initialize media upload — get pre-signed URL(s)
Returns pre-signed URL(s) from LinkedIn for direct client upload. For images and small videos: returns a single uploadUrl. For large videos: returns partUploadRequests (4MB chunks). The API never touches media bytes — the client uploads directly to LinkedIn.
Create a LinkedIn post
Creates a LinkedIn post. For text-only, omit mediaType. For media posts, first use /posts/upload/init to upload, then pass the assetUrn here.
