There was a problem hiding this comment.
It would be helpful to add a comment here describing why this is a with block instead of a decorator. This was actually the subject of a discussion in #801 but it did not go over the possibility of the database mutating at runtime.

Previously, _process_response used a @transaction.atomic decorator, which evaluated the database at import time. Since the database can change at runtime, this caused connection errors in certain scenarios (in my case, multitenant server that uses request host to identify database).
This PR updates _process_response to:
Use a runtime-evaluated database alias inside a with transaction.atomic(using=...) block.
Impact:
Fixes runtime database connection issues.
Ensures profiling and response processing continue to work as intended.
