ApplyAdvice now collects original step IDs before applying rules and
only matches steps in that set. This prevents advice patterns (like "*")
from matching their own inserted before/after steps.
Added test case demonstrating that a "*" pattern only adds advice to
original steps, not to inserted steps.
