feat: implement pipeline step exclusion functionality

- Added support for excluding specific pipeline steps in feature management, allowing users to skip certain steps during execution.
- Introduced a new `PipelineExclusionControls` component for managing exclusions in the UI.
- Updated relevant dialogs and components to handle excluded pipeline steps, including `AddFeatureDialog`, `EditFeatureDialog`, and `MassEditDialog`.
- Enhanced the `getNextStatus` method in `PipelineService` to account for excluded steps when determining the next status in the pipeline flow.
- Updated tests to cover scenarios involving excluded pipeline steps.
