[ENHANCEMENT] Z AI: only two coding endpoints (International/China)

Enhancement

Problem / Value

The Z AI provider currently shows extra endpoints and mixes "coding" vs "standard," which creates confusion and misconfiguration. Limiting to the two official "coding" endpoints simplifies setup and aligns with vendor guidance.

Context

Affects users configuring Z AI in Settings. Z AI requests only:

• International: https://api.z.ai/api/coding/paas/v4
• China: https://open.bigmodel.cn/api/coding/paas/v4

Behavior:

• Keep only these two selectable endpoints in UI and config; remove non-"coding" endpoints.
• Default to International.
• Migrate existing saved settings to the closest option:
  • Old international/intl_standard → International
  • Old china/china_standard → China
• Display labels: "International Coding Plan" and "China Coding Plan".

Constraints/Preferences

Non-breaking migration; keep changes clear in UI; ensure settings validation matches the two endpoints only.

I'm exploring a potential fix to simplify the Z AI provider configuration to only include the two official coding endpoints. I'll open a PR to share progress.

I've opened PR #8688 with my attempt at addressing this issue to simplify the Z AI provider configuration to only include the two official coding endpoints.

The implementation:

• Limits the endpoint selection to only International Coding Plan and China Coding Plan
• Removes non-coding endpoints from the configuration
• Includes automatic migration for existing settings
• Maintains backward compatibility

The PR has some test failures in the CI that may need attention. Feedback welcome!
