The logic method to invoke.
The owning entry's display name, used in log output.
A context-menu callback delegating to the logic method.
Resolution goes through resolveContextItem — the one path every
context-menu consumer shares — so a row identified by an actor-embedded
data-item-id and one identified by its own data-uuid both resolve, and
the two resolvers cannot drift apart (#1188). The speaker comes from the
item's logic, which falls back to a blank speaker for a world (unowned) item
rather than leaving the action context without one.
Build a callback that resolves the context item from the DOM and invokes the named method on the item's logic object.
