feat(kg): 实现 Phase 3.2 Human-in-the-loop 编辑

核心功能：
- 实体/关系编辑表单（创建/更新/删除）
- 批量操作（批量删除节点/边）
- 审核流程（提交审核 → 待审核列表 → 通过/拒绝）
- 编辑模式切换（查看/编辑模式）
- 权限控制（knowledgeGraphWrite 权限）

新增文件（后端，9 个）：
- EditReview.java - 审核记录领域模型（Neo4j 节点）
- EditReviewRepository.java - 审核记录仓储（CRUD + 分页查询）
- EditReviewService.java - 审核业务服务（提交/通过/拒绝，通过时自动执行变更）
- EditReviewController.java - REST API（POST submit, POST approve/reject, GET pending）
- DTOs: SubmitReviewRequest, EditReviewVO, ReviewActionRequest, BatchDeleteRequest
- EditReviewServiceTest.java - 单元测试（21 tests）
- EditReviewControllerTest.java - 集成测试（10 tests）

新增文件（前端，3 个）：
- EntityEditForm.tsx - 实体创建/编辑表单（Modal，支持名称/类型/描述/别名/置信度）
- RelationEditForm.tsx - 关系创建/编辑表单（Modal，支持源/目标实体搜索、关系类型、权重/置信度）
- ReviewPanel.tsx - 审核面板（待审核列表，通过/拒绝操作，拒绝带备注）

修改文件（后端，7 个）：
- GraphEntityService.java - 新增 batchDeleteEntities()，updateEntity 支持 confidence
- GraphRelationService.java - 新增 batchDeleteRelations()
- GraphEntityController.java - 删除批量删除端点（改为审核流程）
- GraphRelationController.java - 删除批量删除端点（改为审核流程）
- UpdateEntityRequest.java - 添加 confidence 字段
- KnowledgeGraphErrorCode.java - 新增 REVIEW_NOT_FOUND、REVIEW_ALREADY_PROCESSED
- PermissionRuleMatcher.java - 添加 /api/knowledge-graph/** 写操作权限规则

修改文件（前端，8 个）：
- knowledge-graph.model.ts - 新增 EditReviewVO、ReviewOperationType、ReviewStatus 类型
- knowledge-graph.api.ts - BASE 改为 /api/knowledge-graph（走网关权限链），新增审核相关 API，删除批量删除直删方法
- vite.config.ts - 更新 dev proxy 路径
- NodeDetail.tsx - 新增 editMode 属性，编辑模式下显示编辑/删除按钮
- RelationDetail.tsx - 新增 editMode 属性，编辑模式下显示编辑/删除按钮
- KnowledgeGraphPage.tsx - 新增编辑模式开关（需要 knowledgeGraphWrite 权限）、创建实体/关系工具栏按钮、审核 Tab、批量操作
- GraphCanvas.tsx - 支持多选（editMode 时）、onSelectionChange 回调
- graphConfig.ts - 支持 multiSelect 参数

审核流程：
- 所有编辑操作（创建/更新/删除/批量删除）都通过 submitReview 提交审核
- 审核通过后，EditReviewService.applyChange() 自动执行变更
- 批量删除端点已删除，只能通过审核流程

权限控制：
- API 路径从 /knowledge-graph 改为 /api/knowledge-graph，走网关权限链
- 编辑模式开关需要 knowledgeGraphWrite 权限
- PermissionRuleMatcher 添加 /api/knowledge-graph/** 写操作规则

Bug 修复（Codex 审查后修复）：
- P0: 权限绕过（API 路径改为 /api/knowledge-graph）
- P1: 审核流程未接入（所有编辑操作改为 submitReview）
- P1: 批量删除绕过审核（删除直删端点，改为审核流程）
- P1: confidence 字段丢失（UpdateEntityRequest 添加 confidence）
- P2: 审核提交校验不足（添加跨字段校验器）
- P2: 批量删除安全（添加 @Size(max=100) 限制，收集失败 ID）
- P2: 前端错误处理（分开处理表单校验和 API 失败）

测试结果：
- 后端: 311 tests pass ✅ (280 → 311, +31 new)
- 前端: eslint clean ✅, tsc clean ✅, vite build success ✅
