feat: Enhance club membership activation and commission pool validation

- Updated AcceptClubMembershipContractCommandHandler to set PackagePurchasedAt to the contract-signing time, ensuring accurate pool charging.
- Modified ActivateClubMembershipCommand to allow specifying a PackageId for forced activation, defaulting to the base package if not provided.
- Improved ActivateClubMembershipCommandHandler to handle new and existing memberships differently regarding pool charging.
- Added validation logic in GetWeeklyCommissionPoolQueryHandler to compare TotalPoolAmount against actual activations.
- Introduced validation fields in WeeklyCommissionPoolDto for tracking discrepancies and expected amounts.
- Updated stored procedures to ensure accurate calculations based on package purchases and to handle empty pools.
- Enhanced protobuf definitions to include validation fields for commission pools and network tree nodes.
- Added mapping for new fields in CommissionProfile and NetworkMembershipProfile.
- Created DiscountProductProfile for mapping discount product requests and responses.
