feat(FN-1103): improve configured workflow steps experience

- Render a dedicated configured-steps state in WorkflowResultsTab with step count, descriptions, and phase badges when results are not yet available
- Keep inline workflow step editing available from the configured state and results state, including add/remove and execution-order controls
- Refine workflow step loading/edit behavior by aligning callback names and fetching step definitions by project context
- Add dashboard styles for the configured workflow step cards and improved edit toggle button treatment
- Expand WorkflowResultsTab and TaskDetailModal tests and add electron-updater type declarations to restore workspace build
