feat: enhance metrics dashboard with new components and data handling

- Introduced `MetricsOverview`, `MetricsMainCharts`, `MetricsDistributionCharts`, `MetricsVelocitySection`, and `MetricsProductivitySection` for improved metrics visualization.
- Updated `MetricsTab` to integrate new components and streamline data presentation.
- Added compatibility fields in `JiraTask` and `AssigneeDistribution` for better data handling.
- Refactored `calculateAssigneeDistribution` to include a count for total issues.
- Enhanced `JiraAnalyticsService` and `JiraAdvancedFiltersService` to support new metrics calculations.
- Cleaned up unused imports and components for a more maintainable codebase.
