After the hard-remove SourceRoot endpoint shipped, two real-world FK
issues surfaced (parent_id self-FK and cross-source-root children) and
one tz-aware datetime issue on PATCH /photos/{id}. All three fixed in
the same session. Trash icon also picks up a spinner during the multi-
second cascade.
Deploy.sh's --force-recreate flag isn't actually recreating reliably;
flagged as open infra question.
