[FIX] 根因修復 - 共享 Volume 下不需對每個容器重複同步

根因：三個容器 (laravel, queue, mqtt-worker) 共享同一份
volume mount (.:/var/www/html)。對 laravel 容器做 tar 同步時，
queue/mqtt-worker 會同時看到檔案變動，導致它們 crash → restart。
接著對 queue 容器做冗餘同步時就會撞上 restarting 狀態。

修復：
1. 只對主容器 (star-cloud-laravel) 同步一次即可
2. 同步完成後等待 worker 容器從短暫重啟中恢復
3. 移除對 queue/mqtt-worker 的冗餘 tar 同步
