feat: AI 意图路由/草稿存储 + Prompts 模块化 + UI 视觉统一 + AI 同意门 + 资源更新

后端:
- 新增 ai_intent_router 意图路由
- 新增 AiEntryDraft 草稿存储 + EF 迁移
- 新增 Prompts 模块化（global/modules/rag/router）
- AI Agent handlers 扩展

前端:
- 新增 AI 同意门 (ai_consent_gate/provider/details_page)
- HealthMetricVisuals 视觉统一
- 设备扫描/管理页面优化
- agent 插图替换 + 趋势指标图标

配置:
- DeepSeek 模型改 deepseek-v4-flash
- .gitignore 加 artifacts/audit
- build.gradle.kts 签名配置调整

+# 项目协作准则
+
+本文件适用于整个 `health_project` 仓库。处理任务时按改动风险分级，验证强度与风险匹配，避免小改动套用重型流程。
+
+## 默认规则
+
+- 默认不执行 `git add`、`git commit`、`git push`、合并、回滚或创建分支；只有用户明确要求时才进行。
+- 保留工作区中用户已有的未提交改动，不覆盖、不清理、不顺带重构。
+- 数据库、上传文件、密钥、生产配置和用户数据不视为普通文件；任何写入、迁移、删除或恢复操作必须先获得用户明确确认。
+- 只修改用户指定的端和功能范围。发现相邻问题可以说明，但不要擅自扩大修改范围。
+
+## 小改动：快速处理
+
+适用于颜色、字号、间距、圆角、文案、图标、单个组件简单布局等不涉及状态、接口和数据的调整。
+
+1. 确认具体文件和修改范围。
+2. 直接完成修改。
+3. 执行格式化。
+4. 进行一次快速编译或静态检查，二者按实际需要选择。
+5. 简要说明改动结果。
+
+不运行完整测试套件，不额外编写计划文档，不提交 Git。
+
+## 中等改动：针对性验证
+
+适用于页面交互、Provider、路由、表单逻辑、接口调用、跨端数据展示、启动脚本和配置修改。
+
+1. 检查相关代码和现有改动。
+2. 修改前简要说明方案。
+3. 完成代码修改和格式化。
+4. 运行静态检查或编译。
+5. 只运行与本次改动直接相关的测试。
+6. 必要时启动对应页面或接口验证一次。
+
+默认不提交 Git。
+
+## 大改动：完整验证
+
+适用于完整新功能、多页面联动、登录、聊天、蓝牙、AI 核心流程、后端结构调整和大范围重构。
+
+1. 阅读相关代码、文档和交接资料。
+2. 与用户确认范围、交互和成功标准。
+3. 分步骤实施，并在关键阶段做针对性检查。
+4. 完成后运行 Flutter 和后端相关完整测试。
+5. 汇总改动、验证结果和遗留问题。
+
+## 高风险改动：确认后执行
+
+适用于数据库迁移或数据修复、大量删除、用户数据、上传文件、签名、生产配置、部署，以及 Git 提交、推送、合并和回滚。
+
+1. 先进行只读检查，确认精确目标和影响。
+2. 向用户说明风险、影响范围和恢复方式。
+3. 必要时先制作可验证的备份。
+4. 获得用户明确确认后再执行。
+5. 执行后进行完整验证并报告结果。
+
+用户在具体任务中的直接指令始终优先于本文件。

-        - 明确要求“记录、录入、保存、记一下”时调用 record_health_data。例如“帮我记录血压116/89”必须生成待确认命令

-# 医生端与管理员端 UI 统一设计
-
-## 目标
-
-在不改变现有业务流程、接口协议和导航结构的前提下，使医生端与管理员端的全部现有页面统一到患者端当前的视觉语言，并在修改过程中进行源码级逻辑检查。
-
-## 范围
-
-- 覆盖 `health_app/lib/pages/doctor/` 下全部现有页面。
-- 覆盖 `health_app/lib/pages/admin/` 下全部现有页面。
-- 覆盖医生端和管理员端侧边栏及其直接使用的共用展示组件。
-- 复用患者端已有的 `AppColors`、主题、卡片阴影、圆角、渐变和页面背景。
-- 检查前端状态处理、异步调用、空数据、错误反馈、导航和字段映射中的明显逻辑错误。
-- 检查后端与医生端、管理员端直接相关的鉴权、数据归属、参数验证和异常处理。
-
-## 不在范围内
-
-- 不新增医生端或管理员端业务功能。
-- 不修改 API 协议、数据库结构或现有权限规则，除非发现明确的高风险缺陷并经用户另行确认。
-- 不重做患者端。
-- 不截图、不做视觉回归平台、不进行真机测试或发布。
-- 不为了视觉统一进行无关的大规模重构。
-
-## 视觉方案
-
-### 页面骨架
-
-- 页面使用患者端的浅灰背景和统一安全区处理。
-- 顶部标题栏保持轻量、透明或白色表面，标题、返回和菜单图标统一使用患者端文字颜色。
-- 页面内容统一使用 16 像素水平边距；主要区块之间保持稳定的 12–16 像素间距。
-
-### 卡片与操作
-
-- 内容容器统一为白色圆角卡片，使用 `AppColors.borderLight` 和轻阴影。
-- 主操作使用患者端紫蓝主渐变；次操作使用浅色表面和边框；危险操作使用现有错误色。
-- 列表项、统计卡片、筛选控件、表单和弹窗使用同一套圆角、文字层级和状态色。
-- 医疗业务的警告、成功、待处理和异常状态继续保持语义颜色，不用装饰色覆盖含义。
-
-### 状态反馈
-
-- 加载状态保留明确进度反馈，避免空白页面。
-- 空状态说明当前没有数据，并保留用户可执行的下一步操作（如果原流程已有操作）。
-- 错误状态显示可理解的中文信息和重试入口（如果原页面已有重载能力）。
-- 长文本和动态数据使用弹性布局与省略处理，降低窄屏溢出风险。
-
-## 组件边界
-
-- 优先使用现有 `AppColors` 和 `AppTheme`，不建立第二套颜色系统。
-- 仅在多个医生端和管理员端页面确实重复时，新增小型共用展示组件，例如页面标题、区块卡片、状态占位和标签。
-- 共用组件只负责展示与交互外观，不持有业务状态、不直接调用服务。
-- 页面继续通过现有 Riverpod Provider 和 Service 获取数据，避免视觉改造改变数据流。
-
-## 逻辑检查原则
-
-- UI 改造过程中检查 `mounted`、重复提交、加载状态复位、空集合、空字段、分页/筛选和导航返回后的刷新。
-- 检查医生与管理员 API 是否要求正确角色，并验证用户或患者数据归属。
-- 明确的低风险页面错误可随 UI 修改修正；涉及鉴权、删除、隐私、医疗数据或接口行为的缺陷先记录并向用户说明，不擅自改变规则。
-- 已知的全局上线风险单独列入最终检查报告，不与本次视觉修改混在一起扩大范围。
-
-## 验证
-
-- 运行 `flutter analyze`。
-- 运行受修改页面影响的现有相关测试；不新增复杂测试框架。
-- 运行一次 Android 编译验证，确认 Flutter 与原生依赖能完成编译。
-- 不运行截图测试、真机测试、iOS 构建或发布流程。
-- 最终说明修改过的页面、发现的逻辑问题、验证结果和仍需人工确认的事项。
-
-## 完成标准
-
-- 医生端和管理员端全部现有页面在颜色、卡片、间距、按钮、文字层级和状态反馈上与患者端一致。
-- 原有页面入口、导航、数据加载和操作流程不被视觉改造改变。
-- 修改代码通过静态分析、相关测试和一次 Android 编译验证。
-- 逻辑检查结果按严重程度清晰列出，高风险业务问题没有未经确认的行为变更。
