Add comprehensive unit tests and documentation for integrations service (#163)

- Enhanced doc strings for all functions, structs, and methods with detailed descriptions
- Added complete test coverage with 15 test cases across constructor, CRUD operations, and data validation
- Created comprehensive tests for IntegrationService methods (Create, Get, GetAll, Delete) with error handling
- Added factory function tests for NewIntegration with parameter validation and edge cases
- Implemented struct field tests for Integration type with nested map validation
- Created test fixtures for all API responses (get, getall, create) with realistic data structures
- Added validation for automatic field setting behavior (Type=Adapter, Virtual=true) in Create method
- All tests pass with proper coverage of complex integration configurations and properties
