feat: 添加用户管理模块 + username/email 唯一约束

- 新增 UserController，实现完整的用户 CRUD 接口
- 扩展 SysUserService 接口和实现类
- 为 sys_user 表添加 username 和 email 唯一约束
- 添加 phone、role_type、status 索引优化查询性能
- 修复 Result 类方法名（failed -> error）

相关接口：
- GET /api/users - 获取用户列表（分页）
- GET /api/users/:id - 获取用户详情
- POST /api/users - 创建用户
- PUT /api/users/:id - 更新用户
- DELETE /api/users/:id - 删除用户
- GET /api/users/teachers - 获取教师列表
- POST /api/users/change-password - 修改密码
- PUT /api/users/profile - 更新个人资料
