SPHINX998andClaude Opus 5.5 b6a157c19c fix(openai): account image input usage on WS passthrough
The WS v2 passthrough relay only read output_tokens_details.image_tokens,
so image generation over WebSocket billed image input tokens at the text
input rate and ignored the hosted response.tool_usage.image_gen breakdown
that the HTTP Responses path already merges (extractOpenAIUsageFromJSONBytes
+ mergeHostedImageGenToolUsage).

The relay now reads image input tokens from input_tokens_details or
prompt_tokens_details, fills missing image input/output counters from
response.tool_usage.image_gen (usage values keep precedence), and carries
ImageInputTokens per turn and in the session aggregate into the
OpenAIForwardResult used for billing.
