WMS主数据结构升级，支持仓库/物料类型等新实体

后端：重构WmsController/WmsService，新增仓库、库区、货位、物料类型等实体及其增删改查接口，支持批量生成网格货位、货位/容器锁定与启用、物料归档与批量清理。数据库模型新增Warehouse、MaterialType、StockEvent等表，调整索引和字段，支持SQLite自动补表/补列及数据迁移，接口兼容旧语义。

前端：wms.ts/types/wms.ts全面适配新结构，升级API路由和类型定义。WarehouseManagementView.vue重构，支持仓库、物料类型管理、货位网格可视化、库存事件展示等。WmsEntityDialog.vue支持新字段编辑及联动选择。新增AreaFacadePanel.vue实现库区网格立面可视化。wmsOptions.ts新增相关常量及UI优化。

兼容性：后端自动迁移旧数据，接口兼容旧绑定语义，提升灵活性、可维护性和可视化能力。
