Fix executable path with spaces breaking launch on Windows

[Copilot]

Description

On Windows, os.execv() reconstructs a command line by joining argv with spaces. When the executable lives under a path with spaces (e.g. C:\Program Files\Meshroom\), the path is split—C:\Program is treated as the executable and Files\... as an argument.

Replace os.execv() with subprocess.call() using a list, which invokes CreateProcess directly and handles quoting correctly.

Features list

• Fix setupInitScriptWindows.py to handle spaces in executable path

Implementation remarks

subprocess.call([sys.executable] + sys.argv[1:]) passes arguments as a list, bypassing the broken command-line reconstruction that os.execv does on Windows. sys.exit() wraps the call to preserve the exit code and prevent the rest of the init script from executing.

@copilot The changes made to localFarmSubmitter.py are irrelevant to the problem, they should be discarded. However the changes in setupInitScriptWindows.py are correct and are indeed solving the issue that was encountered; they should be kept.

Reverted the localFarmSubmitter.py changes in ab20c1b, keeping only the setupInitScriptWindows.py fix.
