Summary of Changes

Hello @hjlarry, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on simplifying the model provider and model entity structures by eliminating the icon_large attribute. This change streamlines the data models and the associated logic for handling provider icons, indicating that the icon_large property is no longer a necessary component of the system's design or functionality.

Highlights

• Removal of icon_large field: The icon_large field has been systematically removed from various Python Pydantic models and TypeScript interfaces across the codebase, including SimpleModelProviderEntity, DefaultModelProviderEntity, SimpleProviderEntity, ProviderEntity, ProviderResponse, ProviderWithModelsResponse, and related types.
• Updated Icon Retrieval Logic: The get_provider_icon method in api/core/model_runtime/model_providers/model_provider_factory.py has been updated to no longer recognize or support icon_large as a valid icon type. Requests for icon_large will now result in a ValueError.
• Cleanup in Service and Test Files: All references and mock data related to icon_large have been removed from service logic in api/services/model_provider_service.py and numerous test files, ensuring consistency with the removal of the field from core entities.
