## Title

    Proposed fix: [LiteLLM Proxy] 401 "Malformed API Key passed in. Ensure Key has `Bearer ` prefix." / "No api key passed in." when master_key is set

## Body

    Recommended action: Send Authorization: Bearer sk-... (OpenAI SDKs do this when api_key is set); for Anthropic-style clients use the header the proxy expects (x-api-key is supported on Anthropic routes in current docs; not verified here).
    
    Option: Use the Bearer scheme [evidence: official_recommended_action]
    Applies when: Custom HTTP clients/agents calling the proxy
    Steps:
    1. curl -H "Authorization: Bearer $LITELLM_KEY" ...
    Expected: Auth succeeds
    
    Evidence basis (self-declared by the contributing chat client): untested.
