feat(frontend): 前端界面优化与使用统计功能增强 (#46)

* feat(frontend): 前端界面优化与使用统计功能增强

主要改动:

1. 表格布局统一优化
   - 新增 TablePageLayout 通用布局组件
   - 统一所有管理页面的表格样式和交互
   - 优化 DataTable、Pagination、Select 等通用组件

2. 使用统计功能增强
   - 管理端: 添加完整的筛选和显示功能
   - 用户端: 完善 API Key 列显示
   - 后端: 优化使用统计数据结构和查询

3. 账户组件优化
   - 优化 AccountStatsModal、AccountUsageCell 等组件
   - 统一进度条和统计显示样式

4. 其他改进
   - 完善中英文国际化
   - 统一页面样式和交互体验
   - 优化各视图页面的响应式布局

* fix(test): 修复 stubUsageLogRepo.ListWithFilters 测试 stub

测试用例 GET /api/v1/usage 返回 500 是因为 stub 方法未实现，
现在正确返回基于 UserID 过滤的日志数据。

* feat(frontend): 统一日期时间显示格式

**主要改动**:
1. 增强 utils/format.ts:
   - 新增 formatDateOnly() - 格式: YYYY-MM-DD
   - 新增 formatDateTime() - 格式: YYYY-MM-DD HH:mm:ss

2. 全局替换视图中的格式化函数:
   - 移除各视图中的自定义 formatDate 函数
   - 统一导入使用 @/utils/format 中的函数
   - created_at/updated_at 使用 formatDateTime
   - expires_at 使用 formatDateOnly

3. 受影响的视图 (8个):
   - frontend/src/views/user/KeysView.vue
   - frontend/src/views/user/DashboardView.vue
   - frontend/src/views/user/UsageView.vue
   - frontend/src/views/user/RedeemView.vue
   - frontend/src/views/admin/UsersView.vue
   - frontend/src/views/admin/UsageView.vue
   - frontend/src/views/admin/RedeemView.vue
   - frontend/src/views/admin/SubscriptionsView.vue

**效果**:
- 日期统一显示为 YYYY-MM-DD
- 时间统一显示为 YYYY-MM-DD HH:mm:ss
- 提升可维护性，避免格式不一致

* fix(frontend): 补充遗漏的时间格式化统一

**补充修复**（基于 code review 发现的遗漏）:

1. 增强 utils/format.ts:
   - 新增 formatTime() - 格式: HH:mm

2. 修复 4 个遗漏的文件:
   - src/views/admin/UsersView.vue
     * 删除 formatExpiresAt()，改用 formatDateTime()
     * 修复订阅过期时间 tooltip 显示格式不一致问题

   - src/views/user/ProfileView.vue
     * 删除 formatMemberSince()，改用 formatDate(date, 'YYYY-MM')
     * 统一会员起始时间显示格式

   - src/views/user/SubscriptionsView.vue
     * 修改 formatExpirationDate() 使用 formatDateOnly()
     * 保留天数计算逻辑

   - src/components/account/AccountStatusIndicator.vue
     * 删除本地 formatTime()，改用 utils/format 中的统一函数
     * 修复 rate limit 和 overload 重置时间显示

**验证**:
- TypeScript 类型检查通过 ✓
- 前端构建成功 ✓
- 所有剩余的 toLocaleString() 都是数字格式化，属于正确用法 ✓

**效果**:
- 订阅过期时间统一为 YYYY-MM-DD HH:mm:ss
- 会员起始时间统一为 YYYY-MM
- 重置时间统一为 HH:mm
- 消除所有不规范的原生 locale 方法调用
