// maskUserPII 审计 M-R16-1：同产品普通 MEMBER 不应拉到他人联系方式。
// 规则：SuperAdmin / 产品 ADMIN / 产品 DEVELOPER，或 caller 看自己，返回原值；其他情况（含普通
// MEMBER 看他人、无 MemberType 的只读视角）把 email/phone/remark 三个 PII 字段置空。
// 返回字段保留其它字段（Username / Nickname / DeptId / Status 等）的原值：
// 业务上"看得到谁在这个产品里"是合理读权限，但"拉通讯录"不是。
//
// 与 MemberList 的口径对齐：MemberListLogic 根本不在响应体里返回 email/phone；UserList/UserDetail
// 则保留"自己 + 管理层"可读的最小授权子集，以便个人资料页、管理台审核流正常工作。
