"""``DELETE /api/profiles/{name}``: a settle-pending delete reports a partial success, not a 500.

Deleting a profile can end with the directory gone and the durable session/routing identity
settlement still pending (#112727, delete side of #111926); ``delete_profile`` reports that as
``ProfileIdentitySettlementPending`` *after* the filesystem half completed. Flattened by the
router's generic exception mapping into HTTP 500, it read as "delete failed" — a dashboard client
then retried into a 404. The endpoint owns the partial-success shape; a genuine filesystem
failure (rmtree) must keep the 500.
