fix(sub2api): 面板管理只保留首页入口，弹窗支持滚动、操作前置

按使用反馈调整（真机验证）：
- 详情页不再重复展示面板管理卡：Key 列表/新建/分组/兑换统一收到首页 Sub2API 卡片的
  「面板管理」入口，详情页只保留用量明细（周期切换 + 柱状图 + 按模型）。
  随之移除详情页已不再使用的 panelKeysState / panelGroups / panelActionMessage 状态收集。
- 修复「面板管理弹窗打开后不能滚动」：AlertDialog 的 text 槽是固定高度且不自带滚动容器，
  内容超过上限会被直接裁剪。改为给 text 槽加 verticalScroll + 高度上限（屏幕高度 72%），
  现在可以正常上下滚动浏览全部 Key。
- 主要操作前置：新建 Key / 兑换卡密 从列表底部移到顶部（原位置在 20+ 条 Key 之后，
  需要滚到底才能看到）；并新增「API Key 列表」小标题区分列表区。
- 弹窗内不再重复标题：组件新增 showHeader 参数，首页弹窗由 AlertDialog title 槽显示标题，
  组件内部标题隐藏（刷新按钮保留）。

验证：compileDebugKotlin、lintDebug 通过；真机（V2172A / Android 15）实测
首页仍只显示今日与近7天、弹窗可滚动、新建/兑换在首屏、详情页无面板管理卡。
注：gradle.properties 的本地路径开关仍未纳入提交。
