build: setup database testing infrastructure with factory-boy

[itisnotyourenv]

Summary

• Setup comprehensive database testing infrastructure with isolated test database
• Added factory-boy for model factories and test data generation
• Created proper Docker setup for test database isolation
• Enhanced test configuration and fixtures for better integration testing

Changes Made

• Dependencies: Added factory-boy>=3.3.3 for test data factories
• Docker Setup: Created docker-compose-test.yml with isolated PostgreSQL test database
• Model Factories:
  • Created tests/utils/model_factories/user.py with UserFactory for test data generation
  • Proper base factory setup with database session integration
  • Fixture integration for seamless test data creation
• Build Tools: Added justfile commands for test database management
  • just test-db-up - Start test database
  • just test-db-down - Stop test database
  • just test-db-reset - Reset test database
• Test Configuration:
  • Updated test config to use dedicated test database (port 5435)
  • Enhanced integration test fixtures with proper database setup
  • Added user factory fixtures for easy test data creation

Test Infrastructure

• ✅ Isolated test database prevents conflicts with development data
• ✅ Factory-boy integration for realistic test data generation
• ✅ Proper fixture setup for database sessions and model creation
• ✅ Docker-based test database for consistent testing environment

Validation

• Test database runs in isolation on port 5435
• User factories create valid test data
• Integration tests can use factory-generated data
• Database fixtures properly manage test sessions
• All existing tests continue to pass
