* feat(infra): migrate payments-dashboard to HCP Terraform (PLAT-79)
Replace the mgmt SAM stack with a prod-only HCP workspace using the afterhours stub-plus-zip-CD seam so GitHub Actions owns function code and Terraform owns infrastructure.
* fix(infra): pin secret and CMK ARNs for bootstrap-plan
hcptf-bootstrap-plan cannot ssm:GetParameter or DescribeSecret, so the first plan must not data-source those values.
* fix(infra): add EIP describe and DynamoDB CMK grants for first apply
Scoped apply missed ec2:DescribeAddressesAttribute and kms Encrypt/Decrypt/GenerateDataKey on the table CMK.
