/**
* Launch Progress JavaScript
*
* This file handles the instance launch and update process, including:
* - Step-by-step progress tracking
* - Stack deployment via Portainer API
* - Error handling for HTTP 502/504 responses
*
* Note: HTTP 502 (Bad Gateway) and 504 (Gateway Timeout) errors are treated as
* potential success cases since they often occur when Portainer is busy but the
* operation may still succeed. In these cases, the system continues monitoring
* the stack status.
