Short answer. space is big. Really big.
If we assume a missile wedge requires 100 km of space, which is almost certainly way too much but is easy to calculate with, and that missiles need to be within 50,000 km of their target, then you can have a wave-front of missile 100,000 km wide, spaced 100 km apart, allowing (100,000/100) 1000 missiles wide and 1000 missiles long, or one million missiles coming in in a plane. That's not counting any use of the third dimension, with missiles coming one behind another.
Note that none of the missile waves at the Battle of Manticore were nearly that size. There's a lot of space for missiles to pass each other en route. I wouldn't be surprised if there were some collisions in e confusion, but ... Space is big. Really big. And both sides share an interest in routing missiles so they don't run into the other side's missiles.
If you want to play with accurate numbers, a missile wedge is 10km wide. That doesn't negate your point though, and actually, about 100km separation between missiles seems pretty logical, as it would allow some maneuvering room for dodging and such.
Overall, though, I'd say that with massive salvos such as BoMA2, that there actually *is* some fratricide, but the amount is so low as to be negligible, and is probably accounted for in setting up the targeting. It just all happens "off camera".
Also, as you mentioned, there is a third dimension to think of. Because of separation issues, when a salvo is launched, there's a slight delay from one missile to the next, as well as angled tubes in the pods (both vertically and horizontally) to assist with separation.
So, while there *is* a chance of collisions, the amount is so small as to be considered nonexistent, but probably only for extremely large salvos.
