feat: Nuke trajectory prediction now accounts for alliance breakage. (#2912)

## Description:

Nuke trajectory prediction now will show interception with allied SAMs
if the alliance will break on nuke launch.

Code was also refactored to be shared a bit more. 

In addition, if an incoming alliance would break if accepted, the nuke
launch will break the alliance.
