DELETE /admin/uploads/{documentId} was gated by a standalone
`X-Admin: true` header check (`IsAdmin`), outside the `Authz` module
entirely and outside the `CasesAdmin`/`StamdataAdmin`/`OrgAdmin`/
`FlagsAdmin` wrappers the four sibling admin surfaces use. It wrote no
AuthzAuditStore row, so a destructive cross-owner document delete never
appeared on /beheer/audit. A repo-wide grep confirmed the only sender of
X-Admin was the backend test itself — no frontend or e2e path depends on
it — so the gate was safe to delete outright.
Routed the endpoint through CasesAdmin (Authz.CanManageCases), the same
wrapper the other admin-cases endpoints use. RB-07 already moved
AuditAuthz onto every *Admin wrapper's allow path, so this gets the
missing audit row for free with no second AuditAuthz call. Deleted the
now-unused IsAdmin function and updated the two comments that referenced
the old X-Admin seam.
Updated EndpointTests.cs's Admin_delete_requires_admin_role to send
X-Role: admin instead of X-Admin: true, and added
AuthzAuditTests.An_admin_upload_delete_is_recorded, which asserts the
cases:manage/allow row count increases by exactly one (a plain
Contains would already be satisfied by this test class's other
cases:manage calls). Verified both tests fail red against the
pre-fix gate.
