feat: 实现项目素材批量删除功能

- 后端实现:
  * 在MaterialRepository中添加batch_delete方法，支持事务处理
  * 在MaterialService中添加batch_delete_materials业务逻辑
  * 添加BatchDeleteResult和BatchDeleteFailedItem数据结构
  * 新增batch_delete_materials Tauri命令接口
  * 实现参数验证和错误处理机制

- 前端实现:
  * 创建useBatchSelection Hook管理批量选择状态
  * 实现BatchDeleteConfirmDialog批量删除确认对话框
  * 在MaterialCard组件中添加批量选择支持
  * 在ProjectDetails页面集成批量选择和删除功能
  * 添加批量操作UI控件（全选/取消全选/批量删除按钮）

- 功能特性:
  * 支持最多50个素材的批量选择
  * 单次最多删除100个素材的限制
  * 详细的删除结果反馈（成功/失败统计）
  * 失败项目的具体错误信息显示
  * 批量选择模式的视觉反馈
  * 完善的用户确认和通知机制

- 测试:
  * 添加批量删除功能的单元测试
  * 测试数据结构创建和验证逻辑

遵循Tauri开发规范和前端UI/UX设计标准，提供安全可靠的批量删除体验。
