fix(editor): remove misleading image line above stack actions (#1584)

Closes #1580. The Command Center header showed the first container's
image directly above stack-wide Start/Stop/Update controls, which implied
those buttons targeted one image. Remove the header image/digest row;
per-container ImageSourceMenu on each row remains.
