feat(slay-the-spire-like): support source entity in effect targeting

Update `getEffectTargets` to accept a `sourceEntityKey`. This allows
"self" targets to correctly resolve to the entity triggering the
effect (e.g., a player or a specific enemy) rather than defaulting
to a hardcoded player reference.
