feat: Bug 图片上传 + 转交 + 操作日志 + 开发中含自测

1. 开发中统计包含 in_progress + testing（自测）

2. Bug 支持上传图片：
   - BugCreateModal 加宽为 max-w-2xl
   - 新增拖拽/点击上传图片区域，转 base64 存储
   - 上传后可预览缩略图、可删除
   - BugDetailDrawer 展示截图列表，点击可放大

3. Bug 支持转交：
   - BugDetailDrawer 操作栏新增"转交"按钮
   - 选人下拉 + 备注输入 → 确认转交
   - transferBug store 方法：更新 assigneeId + 追加日志

4. Bug 操作日志：
   - BugLog interface: create/status_change/transfer/resolve
   - createBug 时记录创建日志
   - changeStatus 时记录状态变更/修复日志
   - transferBug 时记录转交日志
   - BugDetailDrawer 底部展示操作时间线
