feat: ✨ enhance cloning so two-color icons adhere to same-palette rule

[lucas-labs]

Description

I was working on a migrations folder icon (rel: #895) by cloning the folder-database and this was the result:

As you can see, the color in the motif path is from the light-blue palette, while the chosen base color was in the blue-gray palette.

I think this issue occurs due to two factors:

• The original icon being cloned was yellow, and yellow icons tend to have less contrast between dark and light variations
• the blue-gray and light-blue palettes have similar hue values, but very different saturations and luminances.

Since we are only playing with the hue and luminance values of the colors, the result ends up with a color from the light-blue palette instead of blue-gray.

This PR ensures the saturation of the base color is maintained when selecting the motif color, so the resulting color comes from the same palette as the base color.
