remove the nuke mid-flight invincibility

Once #2346 is completed, we should remove mid-flight invincibility

agreed, we should also have the nuke trail preview turn red if it intercepts an enemy SAM, so players can easily tell if it would get shot down or now.

I do think this also relies on #2434 as it gives more options to players for "skill" based rockets

On another Issue and in the dev discord i already shared this worry but will put it here too: removing the invincibility/invulnerability/invisibility will make it impossible to hit some territory, if that territory can only be reached though enemy land with SAMs. Having a red line to point this out improves the experience, but if you don't have another route, the line is just for information; you can still not hit the territory you want to hit in any way. This was the main reason invisibility was introduced originally. So i'm still not sure if this is a good idea, not even when we show a red line to depict targetability.
