refactor(后台契约): 会员详情 plan/status/cycle_kind 收口为 token 枚举

- shared-contracts 新增 ProfileMembershipStatusToken（normal/active）
- AdminProfileMembershipPayload 的 plan/status/cycle_kind 由 String 改为 ProfileMembershipPlanToken/ProfileMembershipStatusToken/ProfileMembershipCycleKindToken，未知值在反序列化即被拒（评审第 13 条）
- module-runtime 补 RuntimeProfileMembershipStatus -> ProfileMembershipStatusToken 的 From 映射
- api-server 的 map_membership 改为直接 .into()，去掉 as_str().to_string()
