test: 🧪 add comprehensive tests for pipeline scheduler and steps

- Introduced tests for `PipelineScheduler` to validate creation, configuration, and job scheduling methods.
- Added tests for various step classes including `ReduceStep`, `FilterStep`, `MapperStep`, and `SequentialStep` to ensure correct initialization and behavior.
- Implemented tests for tracking manager and storage to verify functionality with in-memory and Redis brokers.
- Created utility tests for `PipelineContext` to check result retrieval and error handling.
- Ensured all tests are structured with appropriate fixtures and async handling for robust testing.
