feat: 学生多会员绑定重构 - 支持一个学生被多个会员绑定 

主要变更：
1. 新建 pg_member_student 关联表，实现学生与会员的多对多关系
2. 移除 pg_student.member_id 字段
3. 后端服务层全部改用关联表查询和操作
4. H5 接口支持 relation 字段（父亲/母亲/其他）
5. 前端学生选择弹窗显示已绑定会员数量
6. 更新需求文档

## 附录B：学生多会员绑定重构（2026-02-03）
### B.1 需求说明
**原设计**：一个学生只能被一个会员绑定（`pg_student.member_id` 单值字段）
**新设计**：一个学生可以被多个会员绑定（如爸爸和妈妈都能绑定同一个孩子）
### B.2 数据库变更
#### 新建关联表 `pg_member_student`
```sql
CREATE TABLE pg_member_student (
id BIGINT PRIMARY KEY AUTO_INCREMENT COMMENT '主键',
member_id BIGINT NOT NULL COMMENT '会员ID',
student_id BIGINT NOT NULL COMMENT '学生ID',
relation VARCHAR(20) COMMENT '关系（父亲/母亲/其他）',
create_time DATETIME DEFAULT CURRENT_TIMESTAMP,
UNIQUE KEY uk_member_student (member_id, student_id),
KEY idx_member_id (member_id),
KEY idx_student_id (student_id)
) COMMENT='会员学生关联表';
```
#### 数据迁移
```sql
-- 迁移现有绑定关系
INSERT IGNORE INTO pg_member_student (member_id, student_id)
SELECT member_id, student_id FROM pg_student WHERE member_id IS NOT NULL;
-- 移除 pg_student.member_id 字段
ALTER TABLE pg_student DROP COLUMN member_id;
```
### B.3 后端变更
