front: fix incorrect input saving when switching simulations during a running calculation

When a different simulation is selected while a calculation is still running,
the new simulation’s inputs overwrite the inputs of the ongoing calculation.
This causes a mismatch between the inputs used for the calculation and the results.

Now, the inputs for the simulation being calculated are stored in a different
state variable than the one used for the selected simulation.
