BE: Work Items - visualize records using colors
Summary
This is the backend issue for the requirements found in &10004 (closed). Note that we have a technical spike in #394862 (closed).
Add new widget to support the color highlight feature present in epics.
- The `color` attribute should be stored in a separate table. Do not add a new column to the
issues
table - The corresponding epic feature is behind a feature flag (FF) so we probably want to use a FF for this widget too
