feat: Adobe积分号不锁定额度 + Nano Banana双通道 + 前端显示额度

- Adobe不再区分视频/图片额度，移除ImageLimited/VideoLimited限制
- Adobe积分号quota耗尽不锁定(status不改为quota)，只记录失败用于轮转
- Nano Banana 2/Pro 保留Runway通道，新增nano-banana-2/nano-banana-pro走Adobe
- Adobe模型重命名: runway-nano-banana-2, runway-nano-banana-pro
- 前端管理后台Adobe账号显示积分余额(之前固定显示—)
- README更新模型列表
