feat: Implement Commission and Network Statistics Pages with DTOs and Services

- Added CommissionDashboardPage and CommissionHistoryPage for displaying commission payouts and history.
- Implemented WeeklyBalancePage to show weekly balance details.
- Created NetworkStatisticsPage to display network statistics and tree structure.
- Developed corresponding services (CommissionService, NetworkMembershipService) for data retrieval.
- Introduced DTOs for Commission and Network data structures (CommissionPayoutDto, WeeklyBalanceDto, NetworkStatisticsDto).
- Added mock data generation for testing purposes in services.
- Enhanced UI with MudBlazor components for better user experience.
