Feature request: Ability to change the background card color without removing the thumbnail image

[solokot]

Subj. Reason: sometimes when adding a thumbnail image, Catima chooses a completely unrepresentative background color, which is then used when displaying the card. Currently this can only be fixed by directly editing catima.csv in the backup file.

The request is purely aesthetic and is low priority.

Example:

I'm quite confused why the getDominantColor function from Google's Palette class would pick green as dominant color there. Perhaps we should look at that instead, perhaps the default "swatch" is wrong.

I'm not quite sure what to do here. I'm a bit hesitant to add code to choose this manually as it increases code complexity. It definitely isn't easy right now because image color detection can override headercolor right now.

This is one to look at later perhaps, definitely have a lot of more important issues to deal with first yeah 😅
