 * Compute the last-set idle code for a set of per-channel states.

 * Rules:
 * - Only consider channels in Idle or pending-idle.
 * - Use channel.auxCodeId when non-empty and not "0", otherwise fall back to defaultIdleCode.id.
 * - Skip auxCodeIds that belong to system idle codes.
 * - Resolve name from channel.idleCodeName, then defaultIdleCode.name, then agentState.
