DJANGO CLEANS UP REMOTEUSERMIDDLEWARE ASYNC SUPPORT

Django shipped a series of fixes to RemoteUserMiddleware that simplify async handling and remove redundant user state management across four merged pull requests.
The core issue: RemoteUserMiddleware was duplicating work that the login() function already handles [1]. A cleanup series removes those redundant request.user and auser assignments [1], then strengthens async support with proper method delegation [2]. The team also backfilled missing test coverage for custom RemoteUserBackend implementations in async contexts [3], catching edge cases that would have shipped broken. Error handling got tighter too — ImproperlyConfigured messages now properly handle middleware subclasses [4]. This isn't a breaking change, but it fixes subtle bugs in async authentication pipelines that could cause user state corruption under load. The entire series came from a focused review of the original async middleware PR [2], so expect this pattern to land in the next point release.
