Command Center model analytics group rows by model id only, so dashboard model-name surfaces must infer the provider icon from the model/provider text before handing off to ProviderIcon's fallback-safe renderer.

Standalone GLM model ids such as glm-5.1, glm-4.5-air, and glm-5v-turbo are Z.ai/Zhipu-family models even when the analytics label omits zai/zhipu. Match GLM only at model-id segment boundaries so unrelated words do not hijack the Z.ai provider icon.
