feat: 二期审批引擎扩展与会签/明细/回填/附件分类共享层（#46）

- ApprovalDocumentType SPI + 注册表：新增单据不再改引擎
- ApprovalApproverResolver：会签组、orgLeaderByCode/orgDeputyByCode、租户岗位解析器
- 会签：任务带 group_key/group_name/group_seq，一人多组一次通过，只取消同组待办
- 回填：节点 writableFields、BACKFILL 动作、approval_field_change 留痕
- 附件：新增 VOUCHER 分类并按单据类型校验必传
- 详情：document.fields/lines/lineColumns/groupProgress + permissions.writableFields
- 列表/导出：title/search_text 落库、flowCode 筛选、明细行数/合计金额/会签进度列、明细导出
- sql/05-approval_phase2.sql（可重复执行）
