feat(zai): add GLM-5V-Turbo support for coding plan (#9907)

- Add glm-5v-turbo to OpenRouter, Nous, and native Z.AI model lists
- Add glm-5v context length entry (200K tokens) to model metadata
- Update Z.AI endpoint probe to try multiple candidate models per
  endpoint (glm-5.1, glm-5v-turbo, glm-4.7) — fixes detection for
  newer coding plan accounts that lack older models
- Add zai to _PROVIDER_VISION_MODELS so auxiliary vision tasks
  (vision_analyze, browser screenshots) route through 5v

Fixes #9888
