fix(sub2api): 面板管理入口与余额齐平；用量磁贴压缩为两行

- 「面板管理」从卡片底部移到余额同一行右侧：给 BalanceMainArea 增加 balanceTrailing 槽，
  Sub2ApiBalanceWithUsage 用 Row(verticalAlignment=CenterVertically) 让入口与余额数字齐平，
  不再单独占一行并额外撑高卡片。
- 今日/近7天 磁贴由三行（周期名/Token/次数）改为两行：第一行「周期名 … 请求次数」左右分布，
  第二行 Token 数。磁贴高度 56dp → 44dp，卡片整体更紧凑。

真机验证（V2172A / Android 15）：余额 359.01 位于 y958-1105，面板管理 y956-1037 与之同高；
磁贴两行 y1185-1243 / y1255-1339；点「面板管理」正常打开弹窗（弹窗内标题仍只有一个）。
compileDebugKotlin 与 lintDebug 均通过。
