Add MR widget button to trigger dependency bump Duo flow
What does this MR do and why?
Adds a "Resolve breaking changes with Duo" button to the failed-pipeline widget on the merge request page, which triggers the resolve_dependency_bump/experimental GitLab Duo flow via POST /api/v4/ai/duo_workflows/workflows.
It models the existing "Fix pipeline with Duo" button (mr_duo_fix_pipeline.vue) and reuses the shared DuoWorkflowAction component. The button is gated on a new GraphQL field, Project.duoDependencyBumpBreakingChangesAvailable, which delegates to Project#duo_dependency_bump_breaking_changes_available? (feature flag + project setting + foundational flows + configured consumer).
