[backport cloud/1.40] feat: workflow sharing and ComfyHub publish flow (#9454)

Backport of #8951 to `cloud/1.40`.

Cherry-pick of merge commit `1bac5d9bddd2106b04f330733a45094df379b592`
with conflict resolution.

## Conflict Resolution

- **TopMenuSection.vue**: Kept both queue context menu (from target) and
share tooltip/button (from PR)
- **StatusBadge.vue**: Accepted PR version (adds `class` prop,
`badgeClass` computed with `cn()`)
- **WorkflowTab.vue**: Kept target branch version — PR's context menu
additions depend on `WorkflowActionsList.vue` and
`types/workflowMenuItem` which don't exist on `cloud/1.40`
- **composables/README.md**: Merged both — kept `useValueTransform` from
target, used `useWorkflowPersistenceV2` from PR
- **Textarea.vue**: Accepted PR version (new file, deleted in target)
- **Binary snapshot**: Accepted PR version
- **pnpm-lock.yaml**: Regenerated with `pnpm install`
