chore: refresh GLM model configs

## Summary
- add GLM-5.2 and GLM-4.7-FlashX to Zhipu provider config
- update GLM context/output/pricing tiers from official BigModel docs and pricing
- align Zhipu Coding Plan with official GLM-5.2, GLM-5-Turbo, and GLM-4.7 availability
- sync existing GLM max output values in DashScope configs
- address Copilot review by using extra.pricingTiers consistently

## Validation
- npm run validate
- npm test
- git diff --check
