[Bug] Simulation with warning loaded from file does not match user unit

[SiboVG]

Describe the bug

When saving simulation data to a .ork file, the simulation warnings are also stored. However, any numerical values stored in the warning are stored using the units of the person who saved the sim. If person that saved the sim uses imperial units and I have metric units, then when I open the file, the warning message will have values in imperial units.

The warning message should always adapt to use the user's units.

To Reproduce

1. Set your unit preferences to metrics
2. Open 'A simple model rocket'
3. Open the warnings tab of Simulation 3
4. The deployment speed unit is in mph instead of m/s
5. Rerun Simulation 3, open the sim warning dialog again
6. Unit is now m/s
