fix(gateway): 收敛 sdk.Channel 与 adapter.PlatformAdapter 接口漂移，/admin/channels 恢复枚举

根因：sdk.Channel.Connect 为 2 参 (ctx, config any)，adapter.PlatformAdapter.Connect 为
1 参 (ctx)，Go 无重载 → 4 个渠道（qq-obv11/weixin-ilink/telegram/webhook）只实现 1 参
Connect，类型断言 cap.Value.(sdk.Channel) 恒失败 → /api/v1/admin/channels 恒返回 []。

收敛方向：sdk.Channel.Connect 改 1 参 (ctx)，与 PlatformAdapter 生命周期子集一致；
4 个真实适配器自动满足新接口，adminListChannels 枚举成功。最小改动（不改渠道实现、
不引依赖）。同步修正 sdk_test/registry_test/extra_test 的 mock。
