Phase 2: Replace all deprecated SystemConstants with Package entity reads

- ActivateClubMembership: Load Package, set First/Last fields, PackageId on Cycle+Pool
- AcceptClubMembershipContract: Load Package, set First/Last fields, PackageId on Pool
- CalculateWeeklyBalances: Load base package, use package.MaxBalancesPerLeg/MaxNetworkLevel, set PackageId on NetworkWeeklyBalance
- ProcessUserPayouts: Load base package, use package.MaxNetworkLevel, set PackageId on UserCommissionPayout
- CheckAndProcessDayaLoans: Load base package (IsBasePackage), replace DayaLoanAmount→package.Price, fix hardcoded p.Id==4
- CreateManualPayment: Load base package, replace BasePackageAmount→package.Price, use DiscountMultiplier
- InitiateBasePackagePayment: Remove hardcoded BasePackageId=4, load from IsBasePackage, use package.Price/Id
- VerifyBasePackagePayment: Load Package from order.PackageId, use package.Price+DiscountMultiplier
- ChargeMagicWallet: Load user's package from current cycle, use package.MagicWalletMaxDeposit
- VerifyMagicWalletCharge: Load user's package, use package.MagicWalletMultiplier/MagicWalletMaxDeposit
- OrmCommissionCalculationStrategy: Load base package in both methods, set PackageId on Balance+Payout
- ConfigurationService: Inject IApplicationDbContext, read package values from DB instead of SystemConstants
- UserOrderService: Load user's package for EXIT trigger MagicWalletMaxDeposit check
- UserWalletService: Load user's package for GetMagicWalletStatus display
