P1 Badge Update the secrets submodule for the required IP input

The prod plan/apply workflows check out config/secrets recursively and load prod_db.tfvars, but this commit leaves the submodule pinned at the previous cbceeaaba7de5fa1c944732d2223759fe4a44d2a revision. Because this new variable has no default, Terraform requires the pinned file to define it (HashiCorp variable reference); otherwise the prod CI run triggered by these changes cannot generate a plan or apply. Update the submodule pointer to the revision containing db_ec2_private_ip in the same change.
