[compat-canary] Django adapter breaks against latest Django

The weekly compatibility canary failed building/testing the Django adapter against the latest released Django.

This is an early warning that an upcoming Django version introduces a breaking change (API/class relocation, removed method, etc.) before a customer hits it. See the failing run for the exact error:

https://github.com/awslabs/aurora-dsql-orms/actions/runs/34091472641

Stable releases are unaffected — the supported pinned version still builds. Resolve by updating the adapter for the new Django version, then this issue can be closed (the canary will reopen it if the break recurs).

Start with the failing compatibility-canary run at https://github.com/awslabs/aurora-dsql-orms/actions/runs/34091472641 and inspect the Django adapter and its test output for the exact breaking change. Update the adapter for the latest released Django version, then rerun the canary and confirm the adapter builds and tests pass while the stable pinned version remains unaffected.
