Dependency selectors currently appear at the bottom of the Building Block form. Users often fill in all other inputs first, only to discover at the end that a prerequisite dependency hasn't been provisioned yet (e.g. selecting a GKE cluster before configuring a namespace, selecting a Cloud SQL instance before creating a database, or realizing a required enabler is missing). This forces them to abandon the form and repeat their work after provisioning the missing dependency.

Make dependency placement within the form configurable. Moving the entire dependency section to the top of the form would already resolve the current use cases; there is no identified need to position individual dependencies separately within the form.
