Wire members section to Picker with explicit role changes

Why: P7-A——成员添加从手填账号升级为可搜索人员选择器（@ui Picker：搜索/浏览/键盘/分页），仅提交稳定账号；候选「已加入」标记杜绝隐式身份变更；成员表拆分「专业角色」与「项目身份」（中文标签）两列；身份调整走 rdm.project.member.setRole 显式命令（升/降按钮）。
Evidence: tsc 通过；design-guard 6/6；npm run build 成功；Picker 行为由 UI #53 的 7 用例覆盖。
Impact: RdmMembersSection 重构（member.add/setRole/remove 三命令消费）；rdmManagement 增 setRole payload；account.list 适配层 query 透传+旧基座首页本地过滤降级。
Refs: 提案 r1 §3/P7；UI #53；RDM #345
