Enhanced WSDC registration flow with auto-lookup and account validation:
Backend changes:
- Add accountExists flag to WSDC lookup endpoint
- Check database for existing users with WSDC ID
- Fix Prisma binary target for Alpine Linux Docker containers
Frontend changes:
- Auto-lookup WSDC data after entering 4+ digits (500ms debounce)
- Show live preview dropdown with dancer information
- Display warning if account with WSDC ID already exists
- Block registration and suggest login for existing accounts
- Improve UX with real-time validation feedback
- Add CheckCircle, XCircle, AlertCircle icons for visual feedback
This prevents duplicate WSDC ID registrations and provides immediate
feedback to users, improving the registration experience.

Phase 1, Step 4 completed. Ready for Phase 2 (Core Features).
Phase 1 - Step 2: PostgreSQL Setup
**Infrastructure:**
- Add PostgreSQL 15 Alpine container to docker-compose.yml
- Configure persistent volume for database data
- Update backend Dockerfile with OpenSSL for Prisma compatibility
**Database Schema (Prisma):**
- 6 tables: users, events, chat_rooms, messages, matches, ratings
- Foreign key relationships and cascading deletes
- Performance indexes on frequently queried columns
- Unique constraints for data integrity
**Prisma Setup:**
- Prisma Client for database queries
- Migration system with initial migration
- Seed script with 4 test events and chat rooms
- Database connection utility with singleton pattern
**API Implementation:**
- GET /api/events - List all events (with filtering and sorting)
- GET /api/events/:id - Get single event with relations
- Database connection test on server startup
- Graceful database disconnect on shutdown
**Seed Data:**
- Warsaw Dance Festival 2025
- Swing Camp Barcelona 2025
- Blues Week Herräng 2025
- Krakow Swing Connection 2025
**Testing:**
- Database connection verified ✅
- API endpoints returning data from PostgreSQL ✅
- Migrations applied successfully ✅
All systems operational 🚀
