feat(核算)!: 添加 T+ 正式核算与采集托管

补齐源快照、资料预演、正式导入及工资核算的依赖链路。
新增版本化输入、逐段 FIFO、生成锁和结构化当月调整，
并提供默认关闭的周期采集、有限重试及 Windows 托管。

原始客户资料、私有配置及首页改动不纳入本次提交。

BREAKING CHANGE: 升级前需应用新增迁移，并通过
PAYROLL_MAKER_USER_ID 绑定实际工资制作人，否则业务只读。
旧单批次核算默认关闭；历史兼容需显式启用
PAYROLL_ALLOW_LEGACY_CALCULATION。生产启用和真实金额待验收。

 营销人员绩效工资核算系统。后端 Python/FastAPI，前端 Vue 3，数据存 MySQL，会话与缓存在 Redis。
 
-> 当前进度：登录鉴权与系统管理（用户/角色/操作日志/日志查询）已完成，前端具备应用布局框架。业务模块（基础数据、业务数据、绩效核算、报表）待需求澄清后开发。
+> 当前进度：正式工资闭环及同步运维自动化已完成本地开发验证，支持每周原始采集、有限重试、独立心跳和站内提示，并提供 Windows 托管脚本。生产自动化默认关闭，尚未安装启用；真实金额与整月工资尚未验收，首组样本缺人工指导成本。审核能力保留但默认关闭，多原单更正仍单独跟踪。最新交付见 [开发记录](docs/同步运维自动化与样本核对开发记录_2026-10-30.md) 和 [Windows 操作说明](scripts/windows/README.md)。

+- 在现有账号中明确绑定工资制作人：`PAYROLL_MAKER_USER_ID`。未配置时业务只读，不按管理员或岗位自动放行。真实账号绑定需由维护者核实，不在源码或示例中写入实际用户编号。
+- 应用新增迁移后，T+ 页面提供正式业务导入预览／执行；业务列表“正式核算”准备人工业务资料或核算已导入资料，台账可查看逐段依据。
+- “生成月结快照”首次成功即锁定该月分配；审批退回、重新生成不解锁。历史已生成工资保留，差额计调整单生成当月。
+- 后端接口说明、验证状态和已知边界见 `docs/正式工资闭环开发记录_2026-10-30.md`。旧引擎仅通过 `PAYROLL_ALLOW_LEGACY_CALCULATION` 显式启用作历史兼容，默认关闭，不用于最新规则验收。
+- 集成回归使用 `scripts/run_isolated_tests.py`；原 `.venv` 不可用时，本机使用 `backend/.venv-workbench/Scripts/python.exe`。测试运行器保留隔离库供复查，不删除原开发数据。
+
+审核默认关闭：`PAYROLL_APPROVAL_ENABLED=false`，工资生成直接完成且不产生审批痕迹；如确需系统内复核，显式开启后沿用财务／领导审核和各类审批参数。此配置与旧核算引擎兼容开关独立。

 ## 验收限制
 
-当前只写 MySQL 暂存与管理表，不写工资业务表、不推进时间水位。关联、成本、日期和负向事件的业务规则待客户确认。开发验收先以备份源 10.50.1600 为基准，生产完整版本后补；2022 副本结果不能替代该基准的实测。
+本轮允许已确认的人员、产品、客户进入基础表；不写正式业务、发货、回款、绩效台账、月结、审批或发放记录，不推进时间水位。源库始终只读。日期、含税和人工指导成本已明确；生成凭证资格已按ARAP01来源与有效总账凭证关联核实，未审不等于未生成；平账范围、取价时点、历史余额、特殊更正仍按记录分别待补。
+
+Docker 是当前开发主线，2008 R2 `10.50.1600` 验收后置；2022 副本不能替代同版本实测。实际导入结果、接口、缺驱动处理及启动方法见 `docs/T+基础导入与核算预演开发记录_2026-10-29.md`，字段证据见同日字段与规则差异表。
+
+## 正式工资闭环扩展（2026-10-30，优先于上方上一阶段边界）
+
+已新增 BUSINESS_PREVIEW／BUSINESS_APPLY，允许核实后导入正式业务、发货和回款，正式核算通过独立工资入口执行。源 SQL Server 仍始终只读。新版按同一发货客户名头统一平账、按发货月份指导成本封存；不再按合同拆组或要求重复确认成本月份。
+
+制作人身份由现有账号ID显式配置；审核能力保留但默认关闭，关闭时工资生成直接完成且不写审批步骤。多原单更正仍待讨论。字段、接口、迁移和最终验收边界见 `docs/正式工资闭环开发记录_2026-10-30.md`，客户回执原文见 `docs/客户补充回执核对_2026-10-30.md`。

+`automation.tick` 通过 `tplus-maintain --once` 排队最近到期周的九类原始采集，默认每周一北京时间 02:00 且关闭。明确断连／超时最多两次自动重试，间隔 5／15 分钟；部分失败、配置／资料错误及正式导入不自动重试。人工重试结果接入同一周期，独立心跳不受长查询阻塞。概况的 `automation` 提供状态及异常，不暴露连接凭据。
+
+`tplus-materials --customer-id --month --connection-file --output-dir` 从恢复库只读形成样本核对包；空费用和旧初始化只能作为证据，不能推定零运费／切换余额。用户没有首轮样本人工指导成本，真实金额验收待补。

+
+最终完整单元749项通过。隔离完整集成基线396通过、1个旧夹具权限失败，已修复并在75项受影响模块回归中通过；不将此记录冒充最终代码一次性全量集成通过。V18/V19迁移往返及结构9项通过。覆盖默认无审批痕迹、可选审核开启、客户名头合并FIFO、发货月成本封存、逐段金额与防重、未生成工资月份级联重算、固化分管和当月调整。详细证据见 `docs/正式工资闭环开发记录_2026-10-30.md`。
+
+**禁止直接对原业务库执行集成测试。** 运行 `python scripts/run_isolated_tests.py` 创建受限测试库；夹具在执行前及清理前核验显式标记、名称及真实引擎目标。运行器保留隔离库便于复查，不打印临时凭据。
+
+最新完整集成补验：全部29个测试文件分两套独立数据库覆盖，215＋184＝399项通过，失败0、跳过0。上述旧夹具失败已经修复并关闭；最终结果以本条和开发记录末节为准。完整单元749通过，V18/V19往返及结构9通过。
