fix: remove ext pan id, pan id and network key from settings due to schema bug

[Nerivec]

These are apparently causing weird issues like Koenkk/zigbee2mqtt#28710
Seems the schema logic is not handling the multi-type well and defaulting or something along those lines.
I'm not able to replicate, must be a specific combo.

Since these settings can be set via onboarding, I figure might as well remove them from frontend since it's dangerous if it starts misbehaving.

@Koenkk I think that extra logic should be enough?

Looks good! I agree it's better to hide as it might destroy networks, advanced users that want to change it can always change it in the configuration.yaml.

I was changing settings on cache state/persist cache state/send cached state on startup
