fix(providers): correct Volcengine Plan GLM model id to glm-5.2

The Coding Plan and Agent Plan static catalogs advertised `glm-5.1`, which
is absent from Volcengine's current published Plan model list. Because both
presets are `liveModels: false`, a stale id cannot be corrected by discovery
and surfaces to the user as an upstream model error at request time.
