Let us break this up into pieces. And please read ALL of the post.

Did you happen to miss this sentence?

Before continuing on, please get 'attacking the near orbitals' out of your head. "At All Costs" textev is that "
most of the system's manufacturing and commercial infrastructure (rebuilt with the very latest technology and the aid of massive Manticoran loans and subsidies after Icarus) orbited the planet." Two things, the word 'most' does not equal the word 'all' and I wonder if by 'orbited the planet', RFC was including Lagrange points as a simplifier as he only has so much infodump(tm) he can put in a book and not lose the readers.

That is, btw, one of the reasons why people usually put important orbital industries close to their planet.
And if you do chase off after them, you expose the planet. Which most people in the system, who live on that planet, consider more important than some industrial platform 25 light minutes away on the other side of the sun.
Why would the other industrial platforms be 25 light minutes away? That would be the other side of the system from the planet. There are much closer locations than that for putting infrastructure.
Try to keep up with me here. Here is a
youtube video showing L1-L5 points of the Earth and Moon orbiting around the Sun. L1 of the Earth/Moon is about a light second (300,000km) from Earth. L2 is a little less than 1.5 lightseconds (438,000km) from Earth. L3 is about 1.25 light seconds (375,000km) from Earth. L4 and L5 are a over 1.25 lightseconds (380,000km) from Earth in front and behind the Moon in the Moon's orbit. All of the Lagrange points can have infrastructure orbit there with little to no fuel use. If Zanzibar has a moon, then it will have Lagrange points. Depending on the size of Zanzibar and the size of it's moon, the distances above WILL be different. Since we don't know the size of Zanzibar, then the exact range of ANY Lagrange points is only conjecture, but the fact Zanzibar WILL have Lagrange points is not.
Zanzibar is just under 8 light minutes from it's star and Earth is 8.3 light minutes from the Sun, so lets say that the Earth, Moon, Zanzibar and Zanzibar's moon are the same size since I have the distances above. (Zanzibar doesn't have a moon you say, just wait I say.) I'm sure humans in the 41st century understand NIMBY (No In My Back Yard), I would expect the more dangerous/resource intensive installations would be at Lagrange points. Even the largest fleet (300 wallers) only takes up a half a light second in a STRAIGHT line. We know that fleets are at the minimum a plane, height and width, so a fleet takes up a small part of the volume of a light second and that is what is targetted with missiles. Now a missile at even half the speed of light is only a few seconds from the planet at the distances above, so I can give you the expectation that anything within the distances of the Earth-Moon Lagrange points are probably off limits from attack due to worries about EE violations.
If Zanzibar doesn't have a moon, no problem as there are Lagrange points for the Earth and Sun and those distances are greater. (If Zanzibar does have a moon, then it gets all the Lagrange points I mention.) L1 and L2 are about 5 light seconds from Earth and L4 and L5 are 8.3 light minutes in front and behind of the Earth's orbit. L3 is where you like to put stuff, the opposite side of the Sun from Earth at 18.6 light minutes. I'm betting that 5 light seconds is probably far enough from the planet to consider attacking it. 8.3 light minutes for L4 and L5 are certainly far enough from the planet and L4 and L5 are the largest and most stable of the Lagrange points. Also, the L4 and L5 points are the same distance inside the hyperlimit as Zanzibar and are something a fleet would have to defend. BTW, the L4 and L5 points are at the same distance in front and behind a planet's orbit as the planet is from the star. So Zanzibar's L4 and L5 points are DEFINITELY less than 8 light minutes from Zanzibar.
Mercury, Venus, Mars and the rest all have their own Lagrange points as well. I'm sure hitting Venus with a missile that missed the infrastructure in orbit would get barely a yawn out of the SL. The Sun's (G2) hyperlimit is 21.12 light minutes which is roughly 380 million kms. That means that Mars is 8.5 light minutes inside the Sun's hyperlimit. I would expect the Zanzibar system to have other planets as well. If there are resources to be extracted from those planets, then you would have installations there to extract them. For Earth and Mars, depending on where each are in their orbits, they are 4.2 to 20.9 light minutes apart. Venus and Earth are 2.3 to 8.8 light minutes apart. So, depending on the system layout of Zanzibar, there could be lots of other places for the rest of the infrastruce that isn't around Zanzibar.
Basically, this boils down to 'most' is not 'all' and the other infrastrucure can be far enough away to not worry about EE violations, but close enough for a fleet to defend.
One Light Second is roughly 300,000km. One Light Minute is roughly 18 million kms.
