[MIRROR] improve speed of cascade walls, better description for them + CL for cascade antag [MDB IGNORE] (#13512)

* improve speed of cascade walls, better description for them + CL for cascade antag (#66800)

Cascade walls were processing on object subsystem, they are now in their own subsystem that ticks once per second and should be more reliable even in case of high td
better description for the walls to be more interesting

* improve speed of cascade walls, better description for them + CL for cascade antag
