### What changes were proposed in this PR? Building on the title-bar frame (#8391), this PR adds the collapsible read-only **workflow preview** to the Form View, and the read-only support the embedded editor needs (parent issue #8011). Frontend only. * A "Workflow" strip on the page that opens to show the same workflow editor and mini-map the operator canvas uses, embedded here read-only. It is built the first time the reader opens the strip (a frame after the strip is revealed, so JointJS measures a real size rather than a zero-sized one that misroutes links), then centred. * `structureLocked` on the shared `workflow-editor`: a mode that locks the graph shape (dragging, linking, deleting) without touching the workflow-modification lock the property panel rides on, and suppresses the shared cursor so a read-only view never broadcasts one. It defaults to `false`, so the operator canvas is unchanged. A container `ResizeObserver` keeps the paper sized to its own container (the strip toggles it via `display:none`, which the window-resize handler never hears), and operators already in the graph when this late-mounting editor appears are repainted so a completed run's colours are not missing. * With the flag on the form renders for any workflow, so the preview shows the graph read-only regardless of the workflow's default view. The inputs, running and results are added on top of this by later PRs. #### Screenshot The workflow preview open on the read-only page (the "Workflow" strip expanded to the embedded editor + mini-map): <!-- drag the screenshot here; GitHub replaces this line with the uploaded image --> ### Any related issues, documentation, discussions? Part of the Form View feature (parent issue #8011); stacked on #8391 (title bar) and #8376 (page shell). Until those merge, this PR's diff includes their commits as well. ### How was this PR tested? Unit tests (vitest): `workflow-form.component.spec.ts` (direct construction) and `workflow-form.rendered.spec.ts` (TestBed-rendered template) cover the strip's open/build/close/walk-away behaviour and the rendered bar; the shared `workflow-editor.component.spec.ts` (106 tests) is unchanged and green, confirming the `structureLocked` split leaves the canvas untouched. The page component is at 100% of its TypeScript, and every line added to `workflow-editor` is covered. Three template lines are not exercised: the `<texera-workflow-editor>` and `<texera-mini-map>` embed behind `*ngIf`, which need a real JointJS paper jsdom cannot provide (the editor's own paper code is v8-ignored for the same reason). `ng build` is clean. ### Was this PR authored or co-authored using generative AI tooling?
