feat: 新增AI生图（批量版）节点，模型改名，超时优化与友好报错

- 新增 BatchAsyncImageGenerator 节点（全并发+即时落盘，不怕中途失败丢图）
- 原版 AsyncImageGenerator 移除批量提示词功能，单节点只处理单提示词
- 模型改名：限时特价→次卡，gemini→nano-banana-官方
- 异步节点过滤 官方计费 渠道，仅保留次卡和官方模型
- 单任务超时提升至900s，批量超时改为动态计算（批次数×900s）
- No available channel for model 错误转化为中文友好提示
- 新增 base_async_provider / gemini_async_provider 异步客户端基类
