feat(phase-1): implement PostgreSQL + Prisma + Authentication system

Core Features:
- Complete Prisma database schema with all entities (users, orgs, projects, checks, etc.)
- Production-grade authentication service with Argon2 password hashing
- JWT-based session management with HttpOnly cookies
- Comprehensive auth middleware with role-based access control
- RESTful auth API endpoints: register, login, logout, me, refresh
- Database seeding with demo data for development
- Rate limiting on auth endpoints (5 attempts/15min)

Technical Implementation:
- Type-safe authentication with Zod validation
- Proper error handling and logging throughout
- Secure password hashing with Argon2id
- JWT tokens with 7-day expiration
- Database transactions for atomic operations
- Comprehensive middleware for optional/required auth
- Role hierarchy system (MEMBER < ADMIN < OWNER)

Database Schema:
- Users with secure password storage
- Organizations with membership management
- Projects for organizing redirect checks
- Complete audit logging system
- API key management for programmatic access
- Bulk job tracking for future phases

Backward Compatibility:
- All existing endpoints preserved and functional
- No breaking changes to legacy API responses
- New auth system runs alongside existing functionality

Ready for Phase 2: Enhanced redirect tracking with database persistence
