feat: trial 赠送改为白名单邮箱域名控制

- 新增 EnableTrialEmailWhitelist + TrialEmailDomainWhitelist 配置
- 邮箱注册/登录：加白名单域名判断，域名匹配才赠送 trial
- 设备登录/手机注册：移除 activeTrial，不再自动赠送
- 绑定邮箱(bindEmailWithVerification)：绑定成功后检查白名单+防重复赠送
- 新增 IsEmailDomainWhitelisted 导出函数供跨包调用
- 清理 deviceLoginLogic/telephoneUserRegisterLogic 中的 activeTrial 死代码
