Decompose an update_media_buy patch into the concrete mutations it
requests plus the fine-grained actions those mutations require.
This is intentionally read-only: it does not validate availability or
mutate the request. Buyer code can use it for previews and preflight;
seller/adopter code can use it to dispatch individual patch operations
without re-walking the raw request.
