feat(erp): 采购计划/采购审核/到货跟踪 + 供应商管理

- 采购计划：选合同自动带出明细、合同/供应商表格选择器、批量填充(可生成N行)、卷号/数量列、送审/重新送审流程
- 采购审核：通过/驳回 + 申请意见，每次审核留痕(erp_purchase_plan_audit_log)，计划详情展示审核历史/驳回理由
- 到货跟踪：上传到货Excel按牌号+规格回填明细到货量与状态，列校验/kg→t纠正，满额自动归档
- 供应商管理页(复用既有 erp_supplier 后端)
- 综合搜索(计划号/供货商/合同号)、左右分栏工作台、全局表单按钮对齐修复
- 清理无用旧 erp 页面(看板/需求/订单/收货/退货/汇总)
- DDL 与菜单脚本：docs/purchase-plan-ddl.sql(按 path 解析父目录、可重复执行)
