Description

It's common feedback that users want to have a different set of colors for their charts. We should add an option to customize the color theme. The option will be a global one (and not per user).

If we don't need the color names, then implementing this can be as simple as providing an input box for comma separated list of color hex values in the organization settings page.

Research direction
Examine the existing color palette used in charts, likely in the chart rendering code. Check the organization settings page implementation to add a new field for custom colors. Review related issues #2476 and #2480 for additional context. Implement backend API to store and retrieve the color setting, then update the frontend to apply custom colors to charts.
