refactor(web): 下载盘、RSS、订阅、设置与待处理的剩余去噪项(DEAI-2)

- 下载面板:下载盘只显示「已用 x / 总量」与进度条,暂停线 / 在途 / 预留 / 可清理 / 做种保留收进详情;
  阈值文案统一「暂停线 / 恢复线 / 下载盘满暂停」
- RSS 页去掉与站点页重复的站点表,节标题「RSS 地址」;用途只在非通用时显示
- 订阅:一条都没有时不铺筛选;表单里「空 = 24;0 = 关」等等式改成 placeholder + 一句说明
- 设置:浏览器服务、元数据识别、MCP 说明去掉组件名与实现细节;会话目录与 fake 脚本只在开发构建显示;
  API Key scope 前加中文名;命名模板变量去掉「MP 无」
- 待处理顶部计数卡改成一行筛选按钮
- 智能体悬浮按钮只在没有侧栏的窄屏出现,抽屉打开时不再显示「收起」胶囊
