GUI: rename Pot reset button to "Set" and move it next to its spinbox

Now that doubleSpinBox_pot_temp carries the target temperature, the
old "Pot reset to ambient temperature" label no longer described what
the button does and reserved far more width than a short label needs.
Shortened to "Set" and repositioned immediately to the right of the
Pot [°C] label/spinbox it applies, with both shifted left to fill the
space the long label used to need.
