feat(ui): 安全软件风格主题 + 三阶段进度/日志 + XLSX 支持

- 主面板：阶段1扫描全盘 → 阶段2抽样 → 阶段3抽检，每阶段独立进度条/已用时/分类型 chips

- 日志：按类型着色（命中红/未命中绿/警告黄/阶段青）

- 主题：暗绿底 + 鲜绿/青色强调，圆角胶囊按钮（material::security_dark）

- 抽检：SampleMode 枚举支持按份数/百分比/全部；设置页 C 组动态切换

- 抽检：XLSX 检查器（zip + quick-xml 解析 sharedStrings 与 sheet）

- 扫描：walker 进度回调（已访问、命中候选、当前目录）

- 兼容：quick-xml 0.36 使用 reader.config_mut().trim_text()

- 仓库：新增 .gitignore 忽略 venv/pyc/target/构建产物
