refactor: 统一用户上下文、导入顺序与日志规范

- 控制器移除 HttpServletRequest/HttpServletResponse 参数，新增 util/UserContext 统一获取当前用户 ID 与响应对象，导出接口改用 UserContext.getResponse()
- 引入 Spotless 统一 Java 导入顺序（java/javax → 第三方库 → cn.rosercode），并全量重排
- 日志统一改用 Lombok @Slf4j，替换手写 LoggerFactory
- 补充关键业务日志：登录/注册、交易增删改与批量操作、账单解析导入、DeepSeek 调用耗时与失败、AI 配置与连接测试、通知发送、分类/标签/规则变更
- 全局异常处理补充日志，未捕获异常由 e.printStackTrace() 改为 log.error 记录堆栈
- README 补充功能特性、技术栈与目录结构说明

 # 收支管理系统
 
-个人收支管理系统，支持收入/支出记录管理、分类管理、月度统计与图表展示。
+个人收支管理系统，支持收入/支出记录管理、分类与标签管理、多来源账单导入、自定义归类规则、AI 智能记账、月度统计与图表展示，并提供定时账单导入提醒与系统日志查看。
+
+## 功能特性
+
+### 收支记录
+- 收支记录的增删改查、分页与多条件筛选
+- 批量设置分类、批量设置标签、批量删除
+- 单条记录的「计入统计」开关与「备注隐藏」开关
+- 按当前筛选条件导出 Excel
+
+### 分类与标签
+- 分类、标签的增删改查，新注册用户自动获得一套默认数据
+- 分类图标支持 AI 推荐 Emoji，标签颜色支持 AI 推荐十六进制色值
+
+### 统计与图表
+- 月度收支统计、分类占比、收支趋势、分组统计与概览汇总
+- 基于 ECharts 的可视化图表展示
+
+### 账单导入
+- 支持支付宝（CSV）、微信（xlsx）、美团、交通银行、招商银行（PDF）账单解析
+- 支持 zip 压缩包（含 ZipCrypto / AES 加密压缩包）上传
+- 「解析预览 → 确认导入」两步流程，按交易号去重
+
+### 自定义规则
+- 基于关键词（匹配备注 / 交易对方 / 商品名称）、收支类型、金额区间组合的条件规则
+- 命中后自动应用分类与标签，支持优先级排序与启用 / 停用
+- 账单导入预览阶段展示命中的规则与建议分类 / 标签
+
+### AI 能力（DeepSeek）
+- 交易记录分类与标签的批量 / 单条智能建议，支持一键采纳
+- 自然语言查询解析与自然语言记账解析
+- AI 生成分类、标签，以及 Emoji / 颜色推荐
+- AI 调用用量统计与明细查看
+
+### 定时提醒与通知
+- 按每天 / 每周 / 每月周期提醒导入新账单（默认每月 1 日）
+- 多渠道推送：邮箱 SMTP（如 QQ 邮箱）、Server 酱（推送到个人微信）
+- 渠道管理、测试发送与发送日志查看
+
+### 系统日志
+- 接口访问日志、登录日志的持久化与分页查询
+- 后端运行日志在线查看，支持基于 SSE 的实时推送与筛选
+
+### 账号与多语言
+- JWT 登录认证，注册功能可开关
+- 运行时数据库配置与切换（SQLite / MySQL），无需启动前准备
+- 界面支持中文、英文、日文三种语言
