Device-list limiting (#30997)

* PDA can no longer be linked to multitool

* Ignore previous commit, it would've broken things

* Added SavableAddress field to DeviceNetwork component and PDA for testing. Still need to implement

* System works, borg and pda addresses cannot be saved, but they still connect to the net.

* Suit sensors can no longer be added to network configurators, still work for monitoring purposes.
