Silence httpcore/httpx/openai loggers to stop event-loop wedge (v0.99.94)

Under --debug, httpcore emits a connection-close DEBUG trace from the OpenAI
client's __del__ finalizer. Under load, that finalizer runs during a GC pause
that can land mid-flush of aisbf.log, re-entering the same RotatingFileHandler
and raising "RuntimeError: reentrant call inside BufferedWriter". This cascades
and blocks the asyncio event loop: uvicorn keeps the port bound (LISTEN, Recv-Q
backing up) but stops accepting connections, so the web interface hangs.

Pin httpcore/httpx/openai to WARNING regardless of debug mode so a finalizer can
never emit a DEBUG/INFO record into the reentrant path. Also removes a large
share of the log volume. aisbf's own --debug logging is unaffected.

Verified in production: 0 reentrant errors and 0 httpcore DEBUG lines under live
load after restart; server stable and responsive.
