feat(models): scope deployment and model-file create by organization

Add the organization picker to the model deployment and model-file
download forms (platform-admin "all organizations" view). Filter the
cluster / worker pickers to clusters the chosen org owns, so the created
resource's owner stays aligned with where it runs and a cross-org cluster
can't be selected. Carry owner ids on the cluster / worker options to
drive the filter.
