Implement complete payment system with multiple payment methods, webhooks, and automatic entity updates.
## Components Implemented
### Updated Entities
- Payment entity with paymentMethod field added
- Enums: PaymentType (COURSE, EVENT, MEMBERSHIP, DONATION)
- Enums: PaymentMethod (CREDIT_CARD, DEBIT_CARD, BANK_TRANSFER, CASH, MERCADOPAGO, STRIPE)
- Enums: PaymentStatus (PENDING, PROCESSING, COMPLETED, FAILED, REFUNDED, CANCELLED)
- Polymorphic reference support (referenceId, referenceType)
### API Endpoints
#### Public
- POST /api/v1/payments/webhook - Payment provider webhook
#### Authenticated (Users)
- POST /api/v1/payments - Create payment
- GET /api/v1/payments/my - My payments
- GET /api/v1/payments/{id} - Get payment details
#### Admin
- GET /api/v1/payments - All payments (with filters: status, type)
- POST /api/v1/payments/{id}/confirm - Manually confirm payment
- POST /api/v1/payments/{id}/refund - Process refund
### Services
- PaymentService with complete payment lifecycle management
- Automatic entity updates on payment completion
- Webhook processing for external payment providers
- Refund processing with entity reversal
### Features
- Multiple payment methods support
- Automatic transactionId generation (unique per payment type)
- Checkout URL generation for payment gateways
- Payment webhook processing
- Automatic enrollment activation on course payment
- Automatic event registration confirmation on event payment
- Membership date updates on membership payment
- Refund processing with entity state reversal
- Payment status tracking and filtering
### Integration Logic
#### On Payment Completion
- **COURSE**: Activate enrollment (PENDING_PAYMENT → ACTIVE)
- **EVENT**: Confirm event registration
- **MEMBERSHIP**: Update user membership dates
- **DONATION**: No entity updates required
#### On Refund
- **COURSE**: Drop enrollment (change to DROPPED status)
- **EVENT**: Cancel event registration
- **MEMBERSHIP**: No reversal needed
### Database
- Flyway migration V7 (adds payment_method column to payments table)
- Updated V5 migration to include payment_method in initial schema
## Technical Details
- Transaction ID format: PREFIX-RANDOM (e.g., CRS-A3F2B5C1, EVT-B4E3D2F1)
- Checkout URL placeholder for gateway integration
- Webhook signature validation placeholder
- Polymorphic payment reference support
- Ownership validation for user payments
- Admin-only refund capability

Fix critical configuration issues in pom.xml that could cause compilation failures when using Lombok and MapStruct together.
## Changes
### Dependencies
- Add explicit `<packaging>jar</packaging>` declaration
- Add `lombok.version` property for consistency (1.18.30)
- Add `lombok-mapstruct-binding` dependency (0.2.0) - **Critical for Lombok+MapStruct compatibility**
- Add `spring-security-test` dependency for security testing support
### Compiler Configuration
- Replace `<source>` and `<target>` with `<release>${java.version}` (modern Java 9+ approach)
- Add `lombok-mapstruct-binding` to annotation processor path with correct order:
1. Lombok (generates code)
2. Lombok-MapStruct binding (bridges both libraries)
3. MapStruct processor (uses Lombok-generated code)
## Why These Changes Matter
**lombok-mapstruct-binding**: Without this binding, MapStruct cannot properly process Lombok-annotated classes, leading to compilation errors when generating mappers for entities with @DaTa, @builder, etc.
**Annotation processor order**: The order matters - Lombok must run first to generate getters/setters, then the binding bridges them, and finally MapStruct can use the generated code.
**Release vs Source/Target**: Using `<release>` is the recommended approach since Java 9, providing better cross-compilation guarantees.
