修复的主要问题：

1. **分页切换失效**（AccountsView.vue）
   - 修复 useTableLoader 未解构 handlePageSizeChange 函数
   - 添加 @update:pageSize 事件绑定到 Pagination 组件

2. **内存泄漏修复**（多个文件）
   - UsersView.vue: 添加 searchTimeout 清理和 abortController.abort()
   - ProxiesView.vue: 添加 onUnmounted 钩子清理定时器
   - RedeemView.vue: 添加 onUnmounted 钩子清理定时器

3. **分页重置问题**（UsersView.vue）
   - toggleBuiltInFilter: 切换筛选器时重置 pagination.page = 1
   - toggleAttributeFilter: 切换属性筛选时重置 pagination.page = 1

影响范围：
- frontend/src/views/admin/AccountsView.vue
- frontend/src/views/admin/ProxiesView.vue
- frontend/src/views/admin/RedeemView.vue
- frontend/src/views/admin/UsersView.vue

修复的问题：

1. **搜索和筛选防抖不同步**（AccountsView.vue）
   - 问题：筛选器使用 reload（立即），搜索使用 debouncedReload（300ms延迟）
   - 修复：统一使用 debouncedReload，避免多余的API调用

2. **useTableLoader 竞态条件**（useTableLoader.ts）
   - 问题：finally 块检查 signal.aborted 而不是 controller 实例
   - 修复：检查 abortController === currentController

3. **改进错误处理**（UsersView.vue）
   - 添加详细错误消息：error.response?.data?.detail || error.message
   - 用户可以看到具体的错误原因而不是通用消息

4. **分页边界检查**（useTableLoader.ts, UsersView.vue）
   - 添加页码有效性检查：Math.max(1, Math.min(page, pagination.pages || 1))
   - 防止分页越界导致显示空表

影响范围：
- frontend/src/composables/useTableLoader.ts
- frontend/src/views/admin/AccountsView.vue
- frontend/src/views/admin/UsersView.vue

1. 恢复账号管理批量操作栏缺失的功能按钮
   - 添加"本页全选"按钮支持批量选择当前页所有账号
   - 添加"清除已选"按钮快速清空已选账号列表
   - 在重构拆分组件时遗漏，现已恢复

2. 修复分组管理搜索功能仅搜索当前页的问题
   - 前端：移除本地过滤逻辑，改用后端搜索
   - 后端：添加 search 参数支持，搜索名称和描述字段
   - 支持不区分大小写的模糊匹配
   - 统一所有管理页面的搜索体验

根据 Codex 代码审查报告，修复所有 P0 和 P1 优先级问题。

## P0 紧急修复

### 1. 修复集成测试编译错误
- 更新 group_repo_integration_test.go 中所有 ListWithFilters 调用
- 添加缺失的 search 参数（传入空字符串）
- 修复 4 处旧签名调用，避免 CI 编译失败

### 2. 添加统一的 search 参数输入验证
为所有 admin handler 添加一致的输入验证逻辑：
- group_handler.go: 添加 TrimSpace + 长度限制
- proxy_handler.go: 添加 TrimSpace + 长度限制
- redeem_handler.go: 添加 TrimSpace + 长度限制
- user_handler.go: 添加 TrimSpace + 长度限制

验证规则：
- TrimSpace() 去除首尾空格
- 最大长度 100 字符（防止 DoS 攻击）
- 超长输入自动截断

## P1 改进

### 3. 补充 search 功能的单元测试
新增 admin_service_group_test.go 中的测试：
- TestAdminService_ListGroups_WithSearch
  - search 参数正常传递到 repository 层
  - search 为空字符串时的行为
  - search 与其他过滤条件组合使用

新增 admin_service_search_test.go 文件：
- 为其他 admin API 添加 search 测试覆盖
- 统一的测试模式和断言

### 4. 补充 search 功能的集成测试
新增 group_repo_integration_test.go 测试场景：
- TestListWithFilters_Search
  - 搜索 name 字段匹配
  - 搜索 description 字段匹配
  - 搜索不存在内容（返回空）
  - 大小写不敏感测试
  - 特殊字符转义测试（%、_）
  - 与其他过滤条件组合

## 测试结果

- ✅ 编译检查通过
- ✅ 单元测试全部通过 (3/3)
- ✅ 集成测试编译通过
- ✅ 所有 service 测试通过

## 影响范围

修改文件: 8 个
代码变更: +234 行 / -8 行

## 相关 Issue

解决代码审查中的安全性和稳定性问题：
- 防止 DoS 攻击（超长搜索字符串）
- 修复测试编译错误（CI 阻塞问题）
- 提升测试覆盖率
