Xenoborg jammer now ignores xenoborg associated frequencies (#38005)

* stop jammer from jamming radio of certain frequency

* xenoborg jammer no longer jamms xenoborg radio

* stop jammer from jamming device network signals from certain frequency

* xenoborg jammer no longer jamms xenoborg camera signal

* the old tale of the missing ;

* backwards

* fix issue with readonly

* comments to the frequencies excluded

* triple typo

* clearer summary

* add summary

* fixed 4th hidden typo
