fix(cloudwatch): complete put_metric_data unit dropdown, add missing outputs, fix JSON error handling

- Add all 27 valid CloudWatch StandardUnit values to metricUnit dropdown (was 13)
- Add missing block outputs for put_metric_data: success, namespace, metricName, value, unit
- Add try-catch around dimensions JSON.parse in put-metric-data route for proper 400 errors
