.SYNOPSIS
    Starts the PyTransDatRO FastAPI backend and Vite frontend development servers.

.DESCRIPTION
    Launches Uvicorn (REST API) using the project conda environment and Vite (Web App),
    opens the application in the default web browser, and shuts down both child processes
    cleanly when Enter or Ctrl+C is pressed.
