The page constructs an EmbeddedCounter itself, sets its label through a plain setter
before it is ever rendered, keeps the reference, and embeds it with
ERXWOComponentInstance. The component's own action advances its counter (state that must
survive across requests); the page can also bump it directly by calling a method on the instance;
a note binding is passed alongside; and the instance can be replaced wholesale.
