团队管理：成员擅长标签

- team_members 新增 specialty 列（老库自动 ALTER 迁移，幂等）
- 新接口：GET /api/teams/:id/members 成员列表（仅成员可看）、PUT /api/teams/:id/members/:uid 更新擅长（创建者可改他人，成员仅改自己）；邀请接口支持带擅长
- TeamDialog 重构：团队卡片内成员列表（头像/名称/邮箱/角色/彩色擅长 chip，超 3 个折叠 +N）、行内擅长编辑器（10 个预设点选 + 自定义输入）、邀请时顺手点选擅长预设
- 文档 20-account 同步更新（含活动栏新导航说明）
- curl E2E：邀请带擅长/创建者改他人/自改/越权与非成员 403 全部通过；53 前端测试 + Go 测试全绿
