Contact Image Colour pallet needs updating to match main app

[OliNix]

Contact image colour scheme is not unified with widgets and app.

Apple Watch Ultra "night mode" yields same issue as nightstand mode on iPhone.

Already fixed in my local branch since last week. Will commit and push to the next update.

Removed the commit. Due to the way the contact image view is drawn, changing the color objects to SwiftUI objects causes it to crash. The app instantly recovers, but it then misses an update cycle and doesn't process everything.

We'll keep the issue open to look at it again at a later date.
