perf(backend): offload blocking calls in async paths to threads (#26381)
Audit of asyncio.sleep vs time.sleep and event-loop-blocking calls:

- utils/plugin.py: run pip `install_frontmatter_requirements`
  (subprocess.check_call) via asyncio.to_thread in load_tool_module_by_id,
  load_function_module_by_id, and install_tool_and_function_dependencies.
- retrieval/utils.py: move the synchronous SSRF-guarded requests probe and
  loader.load() in get_content_from_url into a sync helper run via
  asyncio.to_thread.
- routers/audio.py: write uploaded audio to disk off the event loop in
  transcription().
- routers/pipelines.py: write uploaded pipeline file off the event loop in
  upload_pipeline().

The existing time.sleep call sites are all in genuinely synchronous
functions (sync requests/DB drivers/daemon threads) with async
counterparts that already use asyncio.sleep, so no time.sleep -> asyncio.sleep
changes were needed.
