Subject: [PATCH] fix(usage): use frontend gpu_type token for instance-type
 legend

flattenItem receives the unmapped frontend dimension; the instance-type
grouping is 'gpu_type' (mapped to backend 'instance_type' via GROUP_BY_MAP),
so the previous 'instance_type' check never matched and the trend legend kept
showing the raw flavor slug. Check 'gpu_type'. (PR #1240 review)
