feat: 画图台并发重构 + 品牌定制 + 用户备注 + provider/UI 多项修复

画图台(并发出图):
- 不再锁定 UI:点「生成」开独立任务,可连续多次并发
- 结果网格一行5个、最多10张,进行中/成功/失败状态回显,刷新保留进行中
- 生图张数 1/2/3/4,各自独立计费出卡
- 点图=参考图(单张替换/多张替换末位);首尾帧模型点视频=抓末帧设为首帧,否则放大
- /logs 新增 statuses=pending,success 服务端过滤(status IN 专用 SQL)

品牌定制(设置→网站):
- 自定义 Logo 图片 + 子标题(公开页头部 + 管理侧栏)
- 邮件验证码标题改用站点名:{title} 邮箱验证码

提示词复制:
- 去掉复制按钮,点提示词文字即复制(预览/后台日志/图片管理/画图记录),统一弹「指令已复制」
- 新增 utils/clipboard.js:execCommand 回退,非安全上下文(http/IP)也能复制

用户管理:列表加「备注」列,新建/编辑可填改备注(默认空)

provider 修复:
- grok 401 正确判死封号(markTokenFailure 漏了 grok 池)
- grok 视频支持 15s
- custom 上游报错去敏感(抹掉上游 URL/IP,改英文短描述)
- custom 去掉额度耗尽锁定:429/欠费当临时错误,账号保持 active

UI/其它:
- 展示位弹窗浅色主题适配(tab 选中高亮、输入框边框)— 主题变量 + 中心补丁
- 自定义模型:时长可填任意秒数 + 15s 预设
- 首页设置/卡密弹窗去固定高度与滚动条
- 顶部菜单「记录」→「图片」
- 下线 Flow provider(代码移除)
