A production Fortnox migration failed with "SIE-verifikationer kunde
inte importeras atomiskt: canceling statement due to statement
timeout": the atomic import RPC (20260712150000) inherits the 8s
authenticator statement_timeout, so any real-world multi-year SIE file
exceeds it and the whole import is cancelled and rolled back. Same
failure class as 20260629160100 (replace_sie_import / undo_sie_import);
same fix, a function-scoped statement_timeout of 290s sitting under the
calling routes' maxDuration = 300 ceiling.
Migration 20260721144311 is already applied to prod (proconfig verified
carrying statement_timeout=290s); the committed file is byte-identical
under the same version. The new pg-real ratchet pins the config on all
three SIE RPCs because CREATE OR REPLACE FUNCTION silently drops
ALTER FUNCTION settings.
