}LLM Gateway
Test LLM connection
Test that a registered model + credential combination works by sending
a minimal LLM completion call. Returns HTTP 200 with success/failure
for LLM-level results. Returns 4xx for invalid inputs (unknown model,
unknown credential, malformed request) before any LLM call is made.
