refactor: rename model type to size uniformly

there was ModelInfo.type that was essentially looking at the model size / num gpus needed. Since we use modelType to denote embeddings/llm/vlm, changed the ModelInfo.type to ModelInfo.size to better reflect things.
This involves db table "availableModel" schema change

Need to run db:migrate to test this PR.

🟡 Changes recommended

Two fixtures still use type instead of size, breaking frontend type-checking, and replacing the Type chip with Size removes the required LLM/embedding indicator.

What changed in this PR

Renames the model size field from type to size across the catalog, backend, and frontend, distinguishing Small/Medium/Large labels from model capabilities such as LLM or embeddings.

Changes:

• Updates model interfaces, schemas, synchronization, and API mappings to use size.
• Adds a data-preserving database column rename with migration metadata.
• Replaces the model-card Type chip with a Size chip and updates backend fixtures and the changelog.

🟡 Changes recommended

The metadata-chip change removes the existing LLM fallback for models without modelType and displays the internal Text_Embedding value instead of the formatted Text Embedding label.

🟡 Changes recommended

The release note claims a Size chip that neither card variant displays, so the inaccurate claim needs to be removed.

A couple recommended changes to the changelog. Otherwise looks really good!
