fix: 全面代码审查修复 — 安全/类型/持久化/代码质量 (28项)

🔴 CRITICAL (1):
- tauri.conf.json: CSP 从 null 改为最小权限策略

🟠 HIGH (6):
- 新建 capabilities/default.json: Tauri v2 权限约束(store/dialog/clipboard)
- cli: 路径遍历防护 — 拒绝含 ParentDir 组件的输出路径
- HistoryList: 删除/清空同步持久化到 store,历史点击用 formData 回填
- ExportPanel: 移除 console.warn,getCurrentText any→QrState
- useQrEncode: WiFi 密码在历史中脱敏显示(P:***),Store 实例缓存

🟡 MEDIUM (10):
- mode.rs: Kanji fallback 从 UTF-8 字节改为 13-bit 零值占位(段内模式一致)
- mode.rs: Shift JIS 第二字节跳过 0x7F 空洞,修正行内索引
- mode.rs: encode_numeric/alphanumeric 添加 debug_assert! 前置条件
- mask.rs: best_matrix.unwrap()→expect() 附错误信息
- version.rs: ec_info 仅返回 count>0 的 BlockInfo,EcInfo/BlockInfo 加 Debug+Clone
- types/index.ts: HistoryEntry.mode string→ModeType,新增 formData 字段
- qrContext.tsx: 使用缓存 Store 加载历史

🟢 LOW (11):
- cargo fmt 全部文件
- svg.rs: String::new()→with_capacity() 预分配
- patterns.rs: encode_format_info 拆分为两行提高可读性
- png.rs: 提取 fill_module() 辅助函数降低嵌套
- ErrorBoundary: 添加 componentDidCatch 错误日志入口
- QrPreview: dangerouslySetInnerHTML→<img>+data URL(安全),loading 状态指示
- galois.rs/version.rs: 5 处 #[allow(clippy::indexing_slicing)]+安全文档
- 新建 utils/qrText.ts: 集中管理 6 种模式的文本构造,消除 ExportPanel/mode 间重复
