refactor(会员报价): 升级报价快照档位与周期改用枚举

- RuntimeProfileMembershipUpgradeQuoteSnapshot 的 current_plan / target_plan / cycle_kind 由 String 改为 RuntimeProfileMembershipPlan / RuntimeProfileMembershipCycleKind，把非法值挡在类型边界外。
- 模块构造点直接写入枚举；记录侧在 build_runtime_profile_membership_upgrade_quote_record 用 as_str() 转回对外 token，HTTP 契约不变。
- spacetime-client 映射改用 plan / cycle_kind 的 back 映射还原枚举；重新生成 module_bindings。
