Enhances dual porosity result display and plotting

Improves the handling and display of dual porosity results by:

- Adds an option to display a dual porosity label in the UI tree, clarifying the porosity model being used.
- Adjusts the K index calculation for the fracture porosity model in relative permeability plots, ensuring correct indexing.
- Adds a warning message when plotting relative permeability curves for fracture cells since it is not fully supported.
- Replaces direct checks for dual-porosity results with checks against the main grid to determine dual porosity for UI element display.
