## Summary
<!-- Provide a brief summary of the changes you have made and most
importantly what they aim to achieve -->
Based on user feedback, color customisation is important on their iOS
Actions, in widgets and Apple Watch, so this PR adds this option back
but with a little modification, we will first enforce the tile card
design as the standard, if the user wants to use custom colors it has to
enable "custom colors" toggle in actions configuration screen. (I will
also make a PR in Core to be able to configure that via YAML)
This PR also makes the "default" background color for watch items to be
dark instead of white.
