refactor(会员): 会员档位目录移除无用的 sort_order，统一按 rank 排序

- module-runtime catalog.rs：RuntimeProfileMembershipPlanRecord 与种子目录去掉 sort_order，目录单测改为按 rank 断言
- module-runtime domain.rs/commands.rs：后台改价入参与构建函数去掉 sort_order
- spacetime-module profile.rs：profile_membership_plan 表结构去掉排序列，membership_plan_records 改按 rank 升序读取
- shared-contracts runtime.rs：ProfileMembershipPlanResponse 与 AdminUpsertProfileMembershipPlanRequest 移除 sortOrder
- spacetime-client：客户端签名、mapper 与 module_bindings 同步移除 sortOrder
- api-server runtime_profile.rs：响应构建与测试夹具去掉 sortOrder
- admin-web：AdminMembershipPlanPage 移除「排序」输入，档位列表改为按 rank 排序，契约类型同步
- packages/shared：ProfileMembershipPlanRecord 去掉 sortOrder，充值弹层改为直接沿用后端的 rank 顺序
- docs：泥点三池与会员计费后端设计同步目录字段与后台能力说明
