Improves relative permeability plot display

Enhances the relative permeability plot by:

- Adding support for SATNUM and IMBNUM result display in cell reference information.
- Disabling the imbibition curve selection by default and enabling it dynamically based on the IMBNUM value.
- Removing the `satnum` argument from `calculateRelPermCurves` as it's no longer needed.
