Subject: [PATCH] feat(v0.7.0): implement intent rule testing and prompt
 template monitoring

Backend APIs:
- [AC-AISVC-96] POST /admin/intent-rules/{ruleId}/test - Intent rule testing with conflict detection
- [AC-AISVC-97] GET /admin/monitoring/intent-rules - Intent rule statistics
- [AC-AISVC-98] GET /admin/monitoring/intent-rules/{ruleId}/hits - Intent rule hit records
- [AC-AISVC-99] POST /admin/prompt-templates/{tplId}/preview - Prompt template preview with token count
- [AC-AISVC-100] GET /admin/monitoring/prompt-templates - Prompt template usage statistics

Frontend Components:
- [AC-ASA-53] IntentRuleTestDialog - Test dialog for intent rules
- [AC-ASA-54/55] IntentRules monitoring page with hit records drawer
- [AC-ASA-56/57] PromptTemplatePreviewDialog with variable editing
- [AC-ASA-58] PromptTemplates monitoring page with scene breakdown

New files:

+- 状态：**已完成**
+
+#### 4.2 意图规则监控 API (T16.15-T16.17)
+- 文件：`ai-service/app/services/monitoring/intent_monitor.py`（新建）✅
+- 文件：`ai-service/app/api/admin/monitoring.py`（新建）✅
+- API：
+  - `GET /admin/monitoring/intent-rules` ✅
+  - `GET /admin/monitoring/intent-rules/{ruleId}/hits` ✅
+- 状态：**已完成**
+
+#### 4.3 Prompt 模板预览 API (T16.18-T16.19)
+- 文件：`ai-service/app/services/monitoring/prompt_monitor.py`（新建）✅

+- 状态：**已完成**
+
+#### 4.7 意图规则监控页面 (P13-10-P13-11)
+- 文件：`ai-service-admin/src/views/admin/monitoring/IntentRules.vue`（新建）✅
+- 路由：`/admin/monitoring/intent-rules` ✅
+- 状态：**已完成**
+
+#### 4.8 Prompt 模板预览对话框 (P13-12)
+- 文件：`ai-service-admin/src/views/admin/prompt-template/components/PreviewDialog.vue`（新建）✅
+- 状态：**已完成**
+
+#### 4.9 Prompt 模板监控页面 (P13-13)
+- 文件：`ai-service-admin/src/views/admin/monitoring/PromptTemplates.vue`（新建）✅
+- 路由：`/admin/monitoring/prompt-templates` ✅
+- 状态：**已完成**
+
+## 5. 技术上下文
+
+### 项目结构
+- **前端**：`ai-service-admin/` - Vue 3 + Element Plus + TypeScript
+- **后端**：`ai-service/` - Python FastAPI + SQLModel + PostgreSQL
+
+### 核心约定
+- 多租户隔离：所有 API 必须通过 `X-Tenant-Id` header 获取租户 ID
+- 缓存策略：使用 Redis 缓存统计数据（TTL 60秒）
+- Token 计数：使用 `tiktoken` 库，编码器为 `cl100k_base`
+
+### 新增文件清单
