实现数据仪表盘真实数据集成 - 移除所有模拟数据

Browse Source 
后端API实现：
- 创建DashboardApiController，提供完整的仪表盘数据API
- 实现概览数据API：用户总数、付费用户数、今日收入、总订单数、总收入、本月收入
- 实现月度收入趋势API：支持按年份查询月度收入数据
- 实现用户转化率API：计算付费用户转化率和会员等级统计
- 实现最近订单API：获取最新的订单记录
- 实现系统状态API：在线用户数、系统运行时间等

数据库查询优化：
- 扩展PaymentRepository：添加收入统计、月度收入查询方法
- 扩展UserMembershipRepository：添加按状态统计方法
- 扩展MembershipLevelRepository：添加会员等级统计方法
- 扩展OrderRepository：添加最近订单查询方法

前端数据集成：
- 创建dashboard.js API调用文件
- 更新Home.vue：移除所有模拟数据，使用真实API调用
- 实现并行数据加载：概览、月度收入、转化率、系统状态同时加载
- 添加数据格式化函数：数字格式化、金额格式化
- 实现错误处理和后备数据机制
- 更新KPI卡片显示真实数据
- 更新系统状态显示真实数据

数据特点：
- 完全基于数据库真实数据
- 支持实时数据更新
- 包含完整的错误处理
- 提供后备数据机制
- 支持数据格式化显示
