Function resolveChannelInput

aban/aban.ts:441–456

* 把 ManagedGroup 转成可以直接喂给 Api.channels.* 的 channel 参数。 * - channel 有 accessHash → 构造完整 InputChannel，直接走，不触发 GetChannels 兜底 * - channel 无 accessHash（旧缓存或未填）→ 通过 getInputEntity 让 teleproto 自行解析 * - basic group → 返回裸 id（调用方应通过 kind 分流到 messages.* 路径）

(
  client: TelegramClient,
  group: ManagedGroup
)

   * 在管理群中按 userId 解析实体；目标不必与命令同群。
