Move ACCESS_LOG setting to config and use it

Add ACCESS_LOG_ENABLED to src/config/settings.py (defaults to true; accepts true/1/yes) with a comment explaining use cases (disable when fronted by a load balancer or to reduce CI noise). Update src/main.py to import and use ACCESS_LOG_ENABLED for uvicorn's access_log, and remove the now-unused local getenv/os usage. Centralizes the access-log configuration.
