feat(sub2api): 面板管理接入首页卡片；用量明细周期化与按模型筛选修复

首页与用量明细（用户反馈 1-3）：
- 首页 Sub2API 卡片汇总只保留「今日 / 近7天」两个周期，去掉近30天/本月
- Sub2API 用量明细卡默认窗口改为「今天」，进入即看当天数据
- 每日用量柱状图：柱间距按天数自适应（>44 天 1dp），避免近90天时 3dp×N 间距溢出屏幕导致柱子挤没；柱高封顶 0.95、零消耗日 0.02 占位
- 「按模型」真正按时间周期筛选：新增 Sub2ApiRepository.fetchWindowModelStats()，按窗口 start_date/end_date 拉取 model_stats（面板模式走 dashboard/models，Key 模式走 /v1/usage），并新增加载中/错误/空态；切换窗口后自动取消悬空模型选中

面板管理（用户反馈 4）：
- 面板管理 UI 从 ServiceDetailScreen 抽为公共组件 ui/servicedetail/Sub2ApiPanelManagement.kt
- 首页 Sub2API 卡片新增「面板管理」入口，弹窗内嵌同一组件（DashboardViewModel 新增面板状态与动作）
- API Key 不再展示过长明文：列表只显示掩码（前8+后4），新建成功弹窗一次性展示完整 Key 并可复制
- 复制按钮补 Toast 反馈；新建 Key 响应解析兼容 data 对象/字符串/顶层字段，并透传面板 error/message
- 兑换结果不再静默：Toast + 行内快照双反馈；消息消费后置空，连续相同结果也能再次提示
- 面板接口统一校验 HTTP 状态（401/403 明确提示面板登录已失效），不再把登录失效显示成余额 $0.00/空列表
- 面板模式分模型统计窗口与每日明细对齐到近 90 天

其它：SiteIcon 站点图标网络与 SVG 解码移到 Dispatchers.IO；新增 sub2_panel_* 三语文案，修正 sub2_home_no_usage 默认英文资源误写中文。
