Building on the Form View page shell (#8376), this PR adds the title bar and the save it needs (parent issue #8011). Frontend only. * The workflow name, renamable inline exactly as on the operator canvas, with the same "Saved at ..." state beside it. Both follow the workflow's metadata live through the same `workflowMetaDataChanged` subscription the canvas uses, so a rename or save (this page's own, or a co-editor's) refreshes the name, its width, and the saved-at state from one place, and the two views never drift apart. * The debounced save both views share, so an edit in one view is not lost in the other. It saves only the workflow this page opened (never spawning a stray "Untitled workflow" from a payload with no id), preserves a position for every operator (a partial map makes a workflow unopenable), saves once more on the way out and before handing back to the canvas, and reports a failed save rather than losing it silently. * Locks the workflow to read-only on this page (`disableWorkflowModification`): the graph and its properties are shown, not edited. A later PR's authoring mode makes them editable with write access. The read-only preview, the inputs, running and results are added by later PRs. #### Screenshot The title bar (renamable name, "Saved at ..." state, the Canvas / Form View switch) on the read-only page: <img width="1280" height="86" alt="Screenshot 2026-09-03 at 11 18 10 PM" src="https://github.com/user-attachments/assets/b1fa29a8-8b08-4b0c-bfda-51e62d8628f6"; /> ### Any related issues, documentation, discussions? Part of the Form View feature (parent issue #8011); stacked on #8376 (the page shell). Until #8376 merges, this PR's diff includes that PR's commit as well. close #8019 ### How was this PR tested? Unit tests (vitest): `workflow-form.component.spec.ts` (21 tests). As with the shell, the component injects heavy services and child components, so its spec constructs it directly with the shared harness's mocks rather than through TestBed; template rendering is therefore not exercised, but the component and the harness are at 100% of the TypeScript lines this PR adds. The template compiles cleanly under `ng build`. ### Was this PR authored or co-authored using generative AI tooling? Yes. Co-authored with Claude (Anthropic), reviewed line by line by the author before submission.
