Add AuthLayoutClient component and unit tests for authentication layout

- Implemented `AuthLayoutClient` with theme toggle and responsive layout. - Replaced legacy layout implementation in `layout.tsx` with `AuthLayoutClient` for improved modularity and styling consistency. - Added comprehensive Jest tests to verify layout structure, theme toggle placement, and responsive rendering.
Refactor charts to use centralized color palette configuration

Author	SHA1	Message	Date
Felipe Cardoso	e74830bec5	Add `AuthLayoutClient` component and unit tests for authentication layout - Implemented `AuthLayoutClient` with theme toggle and responsive layout. - Replaced legacy layout implementation in `layout.tsx` with `AuthLayoutClient` for improved modularity and styling consistency. - Added comprehensive Jest tests to verify layout structure, theme toggle placement, and responsive rendering.	2025-11-08 09:18:47 +01:00
Felipe Cardoso	51ef4632e6	Refactor charts to use centralized color palette configuration - 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.	2025-11-07 12:41:53 +01:00
Felipe Cardoso	b749f62abd	Complete Phase 9: Charts & Analytics - Added 5 new reusable chart components (`ChartCard`, `UserGrowthChart`, `OrganizationDistributionChart`, `SessionActivityChart`, and `UserStatusChart`) with full TypeScript definitions, responsive designs, and mock data generators for demo purposes. - Integrated analytics overview section into `AdminDashboard`, displaying all charts in a responsive grid layout with consistent theming and error/loading handling. - Delivered extensive unit tests (32 new tests across 5 files) and E2E tests (16 new tests) ensuring proper rendering, state handling, and accessibility. - Updated `IMPLEMENTATION_PLAN.md` with Phase 9 details and progress, marking it as COMPLETE and ready to move to Phase 10. - Maintained 100% unit test pass rate, with overall code coverage at 95.6%, zero build/lint errors, and production readiness achieved.	2025-11-07 12:27:54 +01:00
Felipe Cardoso	3b28b5cf97	Complete Phase 8: Organization Management - Delivered a fully functional and production-ready organization management system, including CRUD operations, member management, and role-based access control. - Added 8 new components and 8 hooks with comprehensive unit and E2E test coverage (49 new E2E tests, 96.92% overall coverage achieved). - Implemented robust error handling, validation, and accessibility across all features. - Updated documentation and marked Phase 8 as COMPLETE, ready to progress to Phase 9 (Charts & Analytics).	2025-11-07 08:43:34 +01:00
