Problem Description

When the FSW stops transmitting data, the green "data received" light does not transition to red again.

How to Reproduce

1. Build Ref demo app
2. Run GDS without starting binary: fprime-gds -n
3. Run binary manually: ./build-fprime-automatic-native/bin/Linux/Ref -p 50000 -a 0.0.0.0
4. Kill binary with Ctrl-C
5. Green light stays lit

Expected Behavior

The green icon should transition to red after a timeout, and then become green again if the binary is restarted.
