Resolve the SohlItem indicated by the closest [data-item-id]
ancestor of target. Lookup goes through the resolved actor's
embedded items so it works whether or not the sheet uses UUIDs, and
falls back to the row's own data-uuid when the actor route comes up
empty (an unowned/world item row, or a surface that emits no
data-actor-id marker).
