Publish CICD or SDK usage metrics

POST 
/usage-metrics

Publishes a usage payload to the usage SNS topic for CICD or SDK traffic. Requires header X-Source of cicd or sdk; other values are treated as invalid. usageMetricsFor must be cicd or sdk (exact case). There is no extra permission check. role_id is recorded in audit logs. This handler catches validation errors inside send_custom_app_usage_sns and returns HTTP 500 with GE-1008, not 400.
