refactor(api): extract AppModelConfig TypedDict definitions into separate module

[jonathanchang31]

Summary

• Extract all TypedDict definitions related to AppModelConfig from api/models/model.py into a new api/models/app_model_config_types.py module
• Re-export all types from model.py to maintain backward compatibility with existing imports

Test plan

• Verify all existing imports from models.model still resolve correctly
• Run existing test suite to confirm no regressions

Checklist

• This change requires a documentation update, included: Dify Document
• I understand that this PR may be closed in case there was no previous discussion or issues. (This doesn't apply to typos!)
• I've added a test for each change that was introduced, and I tried as much as possible to make a single atomic change.
• I've updated the documentation accordingly.
• I ran make lint and make type-check (backend) and cd web && npx lint-staged (frontend) to appease the lint gods

Part of #31096
