fix: dead combatants reappearing as targets via scene token fallback

The combat loop correctly skipped defeated combatants, but their token
IDs were absent from existingTokenIds, so the scene token loop re-added
them. Now building a defeatedTokenIds set from defeated combatants and
checking it in the scene token loop. Also switched from
game.actors.get() to token.actor for the monster HP check so unlinked
monster tokens (synthetic actors) are covered.
