Conversion-runtime report for a service (agent twin of the runtime screen): distribution summary

• histogram + paginated slowest conversions, from the worker’s runtime_ms log lines. Token-gated via the Actor guard (401 without a token). Paginated (offset/page_size, default 100, max MAX_REPORT_PAGE_SIZE; offset capped at MAX_REPORT_OFFSET); 404 if the service is unknown.
