fix: Phase 0 — critical bugs in package purchase handlers

B1: VerifyGoldenPackagePurchase — DiscountBalance was NOT charged (Amount × 2)
    Now charges DiscountBalance same as all other handlers.

B2: VerifyGoldenPackagePurchase — UserPackagePurchase record was NOT created
    Now creates UPP with OrderId and TransactionId.

B3: VerifyPackagePurchase — UserPackagePurchase record was NOT created
    Now creates UPP after wallet charge.

B4: VerifyBasePackagePayment — UserPackagePurchase record was NOT created
    Now creates UPP after wallet change log.

Also: VerifyGolden WalletChangeLog split into 2 logs (Balance + Discount)
      to match the pattern used by VerifyPackagePurchase.
      Transaction description changed from 'پکیج طلایی' to 'پکیج' (generic).

Impact: Only Daya Loan handler was creating UserPackagePurchase before.
        Now all 4 payment paths create it consistently.
