UUID of the defender's combatant — the handler each defense button is
addressed to. The defense-resume executors live on
sohl.document.combatant.logic.SohlCombatantLogic, the click
dispatch routes through the combatant's onChatCardButton, and
sohl.document.chat.gateAutomatedDefenseButtons reaches the actor via
combatant.actor — so the button must carry the combatant uuid, not the
actor uuid.
Display name of the defender token (subtitle + injury-button label).
A targeted defender reduced to the data the attack card needs.
