feat(frontend): 审批与系统设置模块页面接入及业务列表调整

- approval_orders/approval_steps 服务层：submit_order（不 commit 不嵌套
  audit，业务写路径统一收口）+ act 节点动作 + 分页/详情
- 开关关闭=提单即两级「自动通过」留痕（action=3，operator 记系统）；
  开启=财务→领导流转，一驳全驳，驳回必填意见
- 节点准入严格按角色（status=1 仅财务、status=2 仅领导），admin 不代办；
  模块准入 require_roles 依赖工厂（admin/finance/leader，营销后勤待
  澄清 #6 后放开）
- 业务接入：创建/编辑带方案即提单（空方案不提单）；再编辑自动撤回旧
  在途单（node=0/action=4 留痕）；AP 编号冲突 create 内可重取（外层
  重试兜底）、update 直接抛出防静默丢失
- conftest 兜底清理增审批单（AP 前缀）与开关参数种子基线恢复
- 集成 11 例：自动通过/两节点流转/驳回留痕/缺意见 400/节点准入 403/
  admin 不代办/重复操作 400/撤旧建新/模块准入

+
+### 3.1 需求原文（照录）
+
+#### （一）二次分配方案
+
+- 二次分配只出现在合同刚建立时。
+- 合同建立时可手动选择参与二次分配的业务员。
+- 分配比例不要求合计 100%。
+- 审批流程可增加开关配置；关闭时直接生效，开启时走审批。
+- 修改二次分配方案不影响已经结算的月份。
+- 已结算月份如需调整，只能通过调整单或后续月份扣补处理。
+
+#### （二）工作台
+
+- 经营绩效总览
+- 待办事项
+- 风险预警
+- 最近同步/计算/审批动态
+
+#### （三）复核审批
+
+- 营销后勤提交
+- 财务复核
+- 领导审核
+- 审批开关配置
+- 审批意见与版本
+
+#### （四）月结、审批、报表
+
+- 月度结算按确认回款和计算快照生成。
+- 支持负数工资、扣补说明和调整单。
+- 结算后锁定，修改源数据不影响已结算结果，只产生提示、历史记录和后续调整。
+- 导出模板围绕财务复核和领导签字设计。
+
+#### （五）备份恢复与运维检查
+
+- （标题级条目，无细则，用户强调「这个备份恢复很重要」）
+
+#### （六）系统设置
+
+- 公司信息配置：公司名称、logo 等基本信息
+
+#### （七）参数配置强调
+
+- （用户原话）：「业务强调参数配置尽量还是灵活一点，能省去以后很多麻烦」
+
+### 3.2 模块归属与设计要点（开发侧推演，非需求原文）
+
+#### (一) 二次分配方案 → ③ 录入 + ④ 分摊消费 + ⑦ 审批联动 + ④ 调整单衔接
+
+- 「只出现在合同刚建立时」→ 录入入口放业务创建流程（与 `businesses` 创建同事务或紧随其后）；合同建立后是否允许补录/修改未明说，方案修改的留痕方式待设计；
+- 「分配比例不要求合计 100%」→ 余额归属规则需求未说明（3.3-1），存储上只存各参与人比例、不强制校验合计；
+- 「修改不影响已结算月份」→ 月结快照天然隔离（快照固化当月结果），方案表需支持编辑 + 修改留痕；
+- 「已结算月份调整只能通过调整单或后续月份扣补」→ 调整单为统一承载机制，见 (四)。
+
+#### (二) 工作台 → ⑧ 新页面（升级现有 Bento 仪表盘占位）
+
+| 区块 | 数据源（推演） |
+| --- | --- |
+| 经营绩效总览 | ④ 台账/月结（按人/团队/月份汇总） |
+| 待办事项 | ⑦ 待审批单、⑥ 同步失败、回款未指定批次（M2 已有该状态可复用） |
+| 风险预警 | 规则未定义（3.3-5），先落参数化规则容器 |
+| 最近同步/计算/审批动态 | ⑥ 同步日志 + ④ 核算/月结记录 + ⑦ 审批记录 |
+
+#### (三) 复核审批 → ⑦ 新模块
+
+- 三级节点：营销后勤提交 → 财务复核 → 领导审核；
+- 审批对象：月度结算（(四) 联动）；二次分配方案审批（(一) 开关联动）；
+- 「审批开关配置」→ 进 ① 参数体系（BOOL 参数，按审批对象各一）；「关闭时直接生效」= 提交即生成自动通过的审批记录（留痕不断链）；
+- 「审批意见与版本」→ 审批单带版本号：重算/改单产生新版本，旧版本与意见留痕不覆盖；
+- **登录角色体系扩展**：营销后勤/财务/领导是系统新登录角色（`roles` 表基础设施已有；`permissions`/`role_permissions` 自 M1 起闲置待权限清单，此处激活）——打破一期「营销人员不登录」的前提，但与该原则不矛盾（营销人员仍不登录，后勤/财务/领导是职能角色）。
+
+#### (四) 月结、审批、报表 → ④ 月结子块 + ⑦ 审批 + ⑤ 导出模板
+
+- 月度结算 = 台账之上的月度汇总快照（按月生成、含状态机：草稿/待审/已审定/已锁定）；「确认回款」定义待澄清（3.3-3）；
+- 「支持负数工资」与既有裁决「负绩效按公式正常计算（不归零）」一致，无需改公式口径；
+- 调整单：新单据类型（补发/扣减方向、关联月份、扣补说明、审批状态）；
+- 「结算后锁定」：已锁月份的快照金额不可变；源数据修改只产生提示、历史记录和后续调整 —— 与 #19「归属变更不回溯历史」同一哲学，扩展到全部源数据；
+- 导出模板含财务复核栏、领导签字栏、公司信息页眉（依赖 (六) 公司信息配置）。
+
+#### (五) 备份恢复与运维检查 → ⑨（原文无细则，范围由开发定义后交用户确认）
+
+- 备份：MySQL 定时全量（mysqldump，命名卷外置）+ 保留策略 + **恢复演练文档与脚本**（备份不演练 = 没有备份）；
+- 运维检查：容器状态、磁盘空间、备份新鲜度、Redis 键 TTL 抽查、同步日志异常、登录日志异常 → 脚本化健康报告；
+- 用户强调重要 → 建议 M3 期间并行尽早交付（不依赖业务模块）。
+
+#### (六) 系统设置-公司信息 + 参数灵活性 → ① 增量
+
+- 公司信息配置：公司名称、logo（登录页与 ⑤ 导出页眉消费）；
+- 参数灵活性（用户重申方向）：新增审批开关、二次分配、月结相关配置**一律进参数注册表**（16 项清单将扩充），沿用「公式模板（代码内有限集合）+ 参数绑定」既定路线；新增公式形态仍需加模板（一期接受，与「不引入规则引擎」一致）。
+
+### 3.3 待澄清问题（不阻塞收录，对应模块开工前须澄清）
+
+| # | 事项 | 影响模块 | 建议默认处理 |
+| --- | --- | --- | --- |
+| 1 | 二次分配的**分配标的**（绩效金额？折算毛利润？业绩额？）与**余额归属**（合计 ≠100% 时差额归谁）；与已作废的「协助 25%」（#15）是何关系 | ④ 分摊逻辑与台账归属字段 | 未确认前 ④ 只落录入与存储，不实现分摊 |
+| 2 | 二次分配审批开关默认值（开/关） | ⑦ 参数种子 | 按「支付环节按需规默认值参数化」先例：默认关闭（直接生效），可开 —— 待业务确认 |
+| 3 | 「确认回款」的定义：登记即确认 / T+ 同步即确认 / 需人工确认动作？ | ④ 月结取数口径 | 建议需人工确认动作（可在回款确认状态上扩展），待确认 |
+| 4 | 审批角色权限清单：营销后勤/财务/领导的账号归属、可见菜单、操作权限点 | ⑦ 与系统管理 | 开工前业务方给出清单；技术侧激活 permissions/role_permissions |
+| 5 | 风险预警规则：哪些情形预警、阈值多少 | ⑧ | ④⑤ 落地后与业务确认首批规则，先落参数化容器 |
+| 6 | 调整单是否走同一审批链；能否跨月调整已锁定月份 | ④⑦ | 建议走同一审批链；「后续月份扣补」为默认路径，跨月调整需授权留痕 —— 待确认 |
+| 7 | 待办事项的范围（除审批/同步失败外还含哪些，回款未指定批次是否算待办） | ⑧ | 按 3.2(二) 默认清单起步，业务确认后扩充 |
+
+### 3.4 对路线图的影响（本次已修订）
+
+1.1 依赖图、1.3 范围与验收、1.4 里程碑、1.5 依据对照均已并入本批内容；第三章待 3.3 各项澄清后，按第二章同粒度补齐 M3 各增量块的任务级实施计划。
