chore(gateway): replace deprecated asyncio.get_event_loop() with get_running_loop() (#11005)

Browse source 
All 10 call sites in gateway/run.py and gateway/platforms/api_server.py
are inside async functions where a loop is guaranteed to be running.

get_event_loop() is deprecated since Python 3.10 — it can silently
create a new loop when none is running, masking bugs.
get_running_loop() raises RuntimeError instead, which is safer.

Surfaced during review of PRs #10533 and #10647.
