- Around line 116-125: Update _prepare_anthropic_auth and
_prepare_azure_openai_auth to remove every inbound Authorization header key
case-insensitively, regardless of its original spelling, before adding provider
credentials. Preserve the existing credential header assignments and avoid
removing unrelated headers.

Gemini authenticates on
x-goog-api-key, which google-genai sets from thekey the client is constructed with. The extra
Authorization: Bearer <key>added for base_url configurations made Google's frontend look for an OAuth2
principal instead of accepting the key, failing every request with:
401 UNAUTHENTICATED - API keys are not supported by this API. Expected
OAuth2 access token or other authentication credentials that assert a
principal.
custom_headers no longer depends on api_key being passed: it carries
X-Rootflo-Key, which identifies the caller to the proxy rather than
authenticating to Google, and the SDK resolves the key from the
environment on its own.
