run() gains access_log (default on) and log_config parameters. When
enabled, uvicorn's own access log is disabled (access_log=False) and
replaced by an ASGI middleware (adapted from the uvicorn access-log
branch) that logs colored request lines, WebSocket open/close pairs,
and pre-accept rejections in open format.
log_config dicts (uvicorn's default or user-supplied) are patched
best-effort via a registered patch pipeline in fastapi_vue.logging:
swapping in our AccessFormatter, routing our output to a private
fastapi_vue.access logger (uvicorn gates its protocol-level access
logging on uvicorn.access.hasHandlers(), so that logger must stay
handlerless), and filtering stock WebSocket handshake chatter from
uvicorn.error. Non-dict or structurally unexpected configs pass
through untouched.
The middleware is installed by patching Config.load/load_app, hooked
into AccessFormatter instantiation so reload/worker subprocesses
(which re-apply log_config without re-calling run()) are covered.
