Refactor charts to use centralized color palette configuration

Browse Source 
- Introduced `chart-colors.ts` utility to manage reusable color configurations across all chart components (`UserGrowthChart`, `OrganizationDistributionChart`, `SessionActivityChart`, `UserStatusChart`).
- Updated chart components to replace inline color definitions with `CHART_PALETTES` for improved consistency and maintainability.
- Enhanced tooltip, legend, and axis styles to align with updated project theming.
