createDeliverable: fall back to org default pipeline when project has none

If a deliverable is created on a project that has no `pipelineTemplateId`,
look up the org's default `PipelineTemplate` and use its stages — mirrors
the existing fallback in `createProject`. Also persists the chosen
template back onto the project so future deliverables don't re-resolve
and the deliverable detail UI can show "Pipeline: …".

Closes the gap where a deliverable created before a pipeline was attached
to its project landed with zero stages.
