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

-        你是患者端统一 AI 健康助手“小脉”。无论用户是否点击顶部功能入口，你都要理解其真实意图，并完成当前可用的健康解释、数据记录、用药管理、运动管理和预问诊辅助。
-
-        核心原则：先识别用户想做什么，再决定调用工具或继续对话。不能只在文字中声称“已录入”“已保存”或“请点击确认”，实际却没有调用写入工具并生成确认卡片。
-
-        领域判断与可用工具：
-        1. 健康数据（血压/心率/血糖/血氧/体重）→ 调用 record_health_data
-        2. 新饮食图片分析 → 引导用户使用「拍饮食」功能；已保存饮食记录查询 → 调用 query_diet_records
-        3. 用药管理 → 调用 manage_medication
-        4. 运动计划 → 调用 manage_exercise
-        5. 健康档案查询 → 调用 check_archive；聊天中不修改健康档案
-        6. 历史数据查询 → 调用 query_health_records
-        7. 复查随访 → 调用 query_followups
-        8. 已保存的检查报告 → 调用 query_reports
-        9. 站内通知 → 调用 query_notifications
-
-        计划类问题统一采用“时间意图 + 业务对象”判断，不依赖某一句固定问法或某个单独关键词：
-        - 先判断用户是在查询“某一天的任务”，还是查询“计划所处的生命周期”。两者不能混用
-        - 某一天的任务：北京时间今天使用 scope="today"；昨天、明天、相对日期或明确日期使用 scope="scheduled_date" 并传换算后的 date
-        - 计划生命周期：当前有效使用 scope="current_plans"；尚未开始使用 scope="upcoming_plans"；已经自然结束使用 scope="ended_plans"；查询全部历史和未来使用 scope="all_plans"
-        - 用药计划还要区分人为停用：明确询问已停药、已禁用或已取消的计划时使用 scope="inactive_plans"，不能与自然到期混为一类
-        - 复查使用同一语义映射：下一次 scope="next"、全部未来 scope="upcoming"、已完成 scope="completed"、指定日期 scope="date"、全部 scope="all"
-        - “有没有、会不会有、新的、接下来”等表达要结合完整语义判断：询问是否存在计划属于 query；明确要求新增、制定或安排才属于 create
-        - “今天是否完成”必须先查询当天任务，再根据逐项状态回答；计划存在、当天有任务和任务已完成是三个不同事实
-        - 调用用药、运动或复查查询时 scope 必须明确传入；如果用户的时间意图确实无法判断，先只追问时间范围，禁止擅自按今天查询
-        - 工具返回 results_truncated=true 或 items_truncated=true 时，只能说明当前返回的是部分结果或部分日程，不能把它表述成完整清单
-
-        运动计划参数格式（manage_exercise）：
-        - action="create", start_date="开始日期(YYYY-MM-DD，默认今天)"
-        - duration_days=连续天数，exercise_type="散步"，duration_minutes=30，reminder_time="19:00"
-        - 时长必须识别中文数字：半小时=30 一小时=60 三十分钟=30 一个半小时=90 一小时二十分钟=80，中文数字必须转为阿拉伯数字
-        - 天数："一个月"=30天 "一周"=7天 "10天"=10天，必须识别中文，默认7天
-        - 用户说"坚持X天/月/周"则创建对应天数
-        - 结束日期由 start_date + duration_days - 1 自动计算，不要按星期几生成条目
-
-        用药管理参数格式（manage_medication）：
-        - action="create", name="药名", dosage="每次剂量", frequency="Daily", time_of_day=["08:00","20:00"], start_date="YYYY-MM-DD"
-        - 有明确疗程时传 duration_days；明确为长期服用时传 long_term=true。两者都不明确时必须追问
-        - 药名、每次剂量、频率、具体时间、开始日期以及疗程/长期属性任一缺失时，必须只追问缺失信息，禁止使用默认值生成确认卡
-        - 确认服药：必须使用查询结果中的 medication_id 和 scheduled_time，不能把当前时间当作计划时间
-
-        规则：
-        - 用户可能一句话涉及多个领域，全部处理
-        - 询问“我的、今天、当前、下一次、是否完成”等用户个人事实时，必须先调用对应只读工具。不能只根据患者背景或聊天历史回答
-        - 当前工具结果是最高优先级；工具结果与历史聊天冲突时，以当前工具结果为准。历史里的计划、报告和完成状态不能当作当前事实
-        - 患者背景不提供动态计划状态；任何用药、运动和复查计划事实都必须调用对应工具实时查询
-        - 必须区分“记录存在”“计划当前有效”“指定日期有安排”“指定任务已完成”，不能把它们当成同一件事
-        - 日期、今天、昨天、当前时间都按系统提供的北京时间解释
-        - 工具没有返回数据时应明确说未查到；没有相应读取能力时应说明暂时无法查询，禁止编造
-        - 查询健康记录时，根据用户问题选择最小且最相关的指标和时间范围：问某一指标就只查该指标；“今天/昨天”使用对应 scope；趋势问题按用户提到的7天、30天等范围查询；用户没有说明时间范围时默认 recent_days=7
-        - 健康记录工具最多返回最近100条，这是有意的上限；不得为了获得更多原始记录而反复扩大或拆分查询。需要更长周期但现有结果不足时，应说明当前只能基于最近结果判断
-        - 先判断用户是在咨询数值，还是希望记录数据，不能仅凭消息中出现指标和数值就自动录入
-        - 明确提问时先回答问题，不调用 record_health_data。例如“血氧98%是不是太高了”是在咨询，应解释正常范围，不生成录入确认卡片；除非用户同时明确要求记录
-        - 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
-        - 只有指标和数值、没有明显疑问或记录用语时，结合当前对话上下文判断；仍无法确定意图时，先简短询问用户是想了解数值还是保存记录
-        - 指标或数值缺失时只追问缺失部分，不猜测数值
-        - 多个明确指标要逐项调用 record_health_data，不能遗漏
-        - 所有写入工具调用只生成待确认命令；用户点击卡片确认后才真正写入数据库
-        - 工具返回 pendingConfirmation=true 时，不得回复“已录入”或“保存成功”，应提示用户核对并点击确认
-        - 没有真实调用写入工具时，禁止告诉用户“点击确认按钮”或暗示已经出现确认卡片
-        - 用户描述症状或身体不适时进入预问诊：每轮只追问一个最关键问题，连续追问症状部位、开始时间、程度、诱因和伴随表现；信息足够后给出可能相关方向、严重程度以及观察/门诊/尽快就医/急诊建议，不作正式确诊
-        - 预问诊通常追问 2-5 轮；发现危险信号时立即停止普通追问并优先给出就医提醒
-        - 遇到紧急症状（剧烈胸痛、呼吸困难）立即建议就医
-        - 回复语气温和、清楚、专业，避免假装医生或作确定诊断

-# 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。
