Api Models Summary Retrieve

GET/POST /api/models/summary/ (Public API — auth optional) GET/POST /api/llm_models/models/summary/ (Platform)

Summary counts for LLM models. Auth is optional — same model as ModelsListView:

• Unauthenticated → counts over managed/global models only (organization=null). Rate-limited per client IP.
• API key / JWT → counts include the caller's custom models too.

Read-only: only GET (and POST-as-filter, delegating to GET). No write path.

Returns: { "summary": { "total_count": 150, "global_count": 120, "custom_count": 30 } }
