Replace all mocks with real implementations in test_declarative_framework.py

- Created TestableDeclarativeModel class extending Model
- Removed unittest.mock imports (Mock, AsyncMock, patch)
- Replaced mock_model.generate.side_effect with set_generate_side_effect()
- Replaced mock generate functions with testable model methods
- Created IntegrationTestModel for integration tests
- Fixed retry mechanism test to use model's call_count
- All mocks replaced with real test implementations

Part of fixing Issue #48 to remove all mock objects per NO MOCKS policy.
