Introduce a new database table `department_selfserve_path_confirmations` to store path confirmations related to department configurations. Update `PingApiTest` to verify additional keys, ensuring `backend_version` and `api_commit_sha` are checked in the response.
- Introduced `selfserve_enabled` property for `department_lanes` with schema update, object properties, and associated methods/tests.
- Enhanced `selfserve_wash_flow` and session logic to respect lane self-serve settings, including block handling and task filtering.
- Updated API routes and Studio Graph projections to include `selfserve_enabled` in payloads and progress callbacks.
- Added unit tests for session statuses, lane configuration, and blocking behavior due to disabled self-serve settings.
- Introduced `selfserve_task_attachment_payloads` class for managing task attachments, including formatting and download URL generation.
- Added unit and API tests to validate attachment handling in self-serve tasks and customer-scoped workflows.
- Enhanced wash start simulation and studio graph projections to integrate task attachment data.
- Add `DepartmentLaneDynamicImageRouteTest` to verify dynamic image preview handling for studio lanes.
- Introduce `selfserve_machine_signal` class to standardize signal normalization, recording, and gateway signal management workflows.
- Add `selfserve_virtual_hardware` class to handle virtual hardware configurations, including gateway and binding management.
- Enhance structure with auxiliary methods for payload normalization, workspace merging, and validation warnings.
- Introduce `requestBooleanFlag` method for consistent boolean parameter handling with default values.
- Add `activate_machine` and `sync_relay_state` parameters to `synchronizeSession` for more flexible relay and machine activation control.
- Update methods, routes, and tests to integrate the new session synchronization parameters effectively.
- Enhance debugging support with additional metadata in simulation and payload captures.
Introduce `department_selfserve_studio_layouts` table for department-specific layouts and implement advanced auto-layout functionality in the DepartmentSelfServeStudio module. Added custom node definitions, updated styling, and integrated new logics for sorting and visualizing nodes in the Vue Flow interface.
