feat(cockpit): 报警/工单读模型与 district 片区契约

按决策票 06 / 规格 10 / 执行票 12 的六项维护者裁定实施：把旧自由串
`region`（实测恒为「未分区」，适配器写死 null）改为权威片区 `district`，
并补齐工单读模型的未关联显式提示。

## 片区口径单源（新增）

`cockpit/foundation/CockpitDistrict.java`：归一（codeOf/nameOf）、点位归纳
（aggregate：多设备不一致或无设备→未分区）、入参解析（parseQuery：只认
0/1/2/UNASSIGNED，脏值→400）、匹配（matches）与「未分区」常量。

权威来源＝`equipment_base.district`（0城南/1城北/2太常，见 DistrictEnum）。
`monitor_point` 无片区列、`PipeNetworkBase` 无该字段、`equipment_point_rel`
实测 0 行，故点位按「经其上挂设备归纳」、设施一律未分区 —— 如实呈现，
**不加数据库列、不用行业或管理单位冒充**（维护者裁定）。

## 六族统一改造

- 地图摘要：`map-snapshot?district=...`；点位/设备双字段
  `district`(Integer,未分区 null)+`districtName`；`mapFilter` 增
  `districtFilter`(NONE/ASSIGNED/UNASSIGNED) —— 「未筛」与「只看未分区」
  编码都是 null，必须靠该字段区分。
- 运行监测：distribution/situation 的 `regionDistribution` →
  `districtDistribution`，marker 双字段。
- 基础设施：base-archives 同上；管理信息按决策票 06 **删除**
  `organizations`/`ownershipDistribution`/`totals.unmaintainedCount`/
  `totals.organizationCount` 与 Organization/Ownership 内部类，改回
  `districtIndustry[]`（片区×行业的设施/设备计数）。
- 事件多维分析：维度 REGION/区域 → DISTRICT/片区，桶码 0/1/2/UNASSIGNED。

## 工单读模型（范围 1）

`CockpitWorkOrderSummary` 新增显式 `associatedWithCurrentEvent`，
`CockpitWorkOrderReadResponse` 新增 `unassociatedWorkOrderCount`：
设备维度返回该设备已有全部工单，其中未与当前报警关联者被**显式**标出，
调用方不必从 `eventAssociation == null` 反推（本票验收句「未关联当前报警
的工单明确提示」）。关联键以真实库核实为准：
`alarm_data.work_order_id = work_order.order_id`（维护者原述
`alarm_no = order_no` 经实测命中 0 条，且两列均不存在）。

## 验证

`mvn -o -pl pipe-network-service/zksy-admin -am compile` 通过；
`-Dtest=Cockpit*Test` **311/311 通过**（基线 299，新增 12 例，覆盖
district 归一/脏值 400/UNASSIGNED 筛选/点位归纳/删字段形状/关联标记）。

`docs/cockpit/README.md` 同步新契约与片区章节。

未提交前未部署，运行实例仍是旧契约；真实环境复验追加到执行票 17。
