feat(groups): 放行 kimi/zhipu/deepseek 平台分组创建入口

PR #5666 引入 CN 平台后,路由/调度/前端类型均已支持 CN 平台分组,但分组
创建入口两头缺失:后端 Create/UpdateGroupRequest 的 platform oneof 白名单
与前端 GroupsView 平台选项都没有三平台,导致 CN 账号「无可用分组」、整条
流量链路不通(composite 不能作为替代:CN 不可为 composite 路由目标)。

- group_handler.go: 两处 oneof 加 kimi/zhipu/deepseek;composite 路由目标
  白名单有意不动(DetectModelPlatform/isConcreteRequestPlatform 均无 CN 分支)
- GroupsView: platformOptions/platformFilterOptions 补三项;两处徽章配色链
  按 platformColors.ts 色系补 CN 分支
- i18n: admin.groups.platforms 补 kimi/zhipu/deepseek 键(zh/en),缺键时
  分组徽章/GroupRPM/RateMultipliers 弹窗/ChannelsView 会渲染原始 key
- GroupBadge: badgeClass/labelClass 补 CN 配色
- 新增表驱动测试:9 平台 Create/Update 全放行、非法值(别名/大小写/空格)
  全拒绝、composite target 对 CN 保持拒绝的守卫
