fix(talk): 修正成员搜索的 Manager 调用并把成员判定归一为 bytes

- SearchCompanyUsers 与 _IsCompanyUser 改用 RoleManager.GetCompanyUserUUIDs
  （原误用 CompanyManager，该类没有此方法，成员搜索接口 500）
- _IsCompanyUser 统一转 bytes 后再比对（GetCompanyUserUUIDs 返回 UUIDObj 集合，
  UUIDObj 与 bytes 的 hash 不同，原写法成员判定恒为 False，导致邀请成员必失败）
- 菜单链接由 pages/talk/index.html 改为 pages/talk.html
  （前端 normalizeMenuPath 只去 pages/ 前缀与 .html 后缀，原写法规范化为 /talk/index 会 404）
