fix: filter comfy/ subdirectory from sys.path before loading server.py

Browse Source 
nodes.py inserts the comfy/ subdirectory into sys.path, which shadows
the top-level utils/ package (comfy/utils.py vs utils/__init__.py).
This breaks server.py's import chain when app.frontend_management
does 'from utils.install_util import ...'.

Filter out the comfy/ subdirectory temporarily before loading server.py,
then restore it immediately after. Use list comprehension instead of
sys.path.remove to satisfy the gap-window test assertion.
