fix: carry signals as NetworkValue, not NetworkToggle

v1.0.0 loaded cleanly and did nothing in game. Every vanilla use of
NetworkToggle and NetworkToggleReceiver -- all three of them -- sets
IncludeInPhysical = false. They are blueprint stat-display plumbing and
carry no signal on a real ship, so the receivers always read off, the
vent gate stayed open, and radiators behaved exactly as in vanilla.

Broadcast 1/0 through NetworkValue and threshold it back into a toggle
on the receiving side. That is what the thermal amplification pump uses
to drive physical behaviour, and vanilla never sets IncludeInPhysical on
it anywhere.

Also repoint the radiator's power indicator at the gate, so an auto-idled
radiator is visibly idle instead of looking identical to a working one.

Tests grow a guard against the blueprint-only types, plus a check that
re-verifies that premise against the installed game data so the guard
cannot go stale, and a name-collision check against vanilla components.
