Deploy to S3 / deploy (push) Successful in 23sDetails
Every business action now lands in a new append-only audit_log table with the
verified signed-in identity: logins, closing create/delete/reopen, file upload
(incl. replacements) and delete, processing runs, export generation and
downloads. Rows carry no FK so history survives a closing's deletion.
Admins (new users.is_admin flag, granted via `manage.py set-admin <username>`)
can read it at /api/audit and in a new Audit Log page in the sidebar; everyone
else gets 403 and no nav entry. login/me responses now carry is_admin.
