"""Reassign security group/category/privilege xml-ids from the old module name.

Pre-Phase-0, the three fusion security groups (user, manager, admin), the
module category and the privilege all lived in module='fusion_accounting'.
Post-Phase-0 (Task 16) they moved into module='fusion_accounting_core'.

Odoo loads the XML from the new location on upgrade, but the existing
ir_model_data rows still reference the old module. This script rewrites them.

Both fusion_accounting_core and fusion_accounting_ai ship an equivalent
UPDATE — whichever post-migration runs first wins the rehoming, the other
is a no-op. This redundancy protects the common case where the two modules
are upgraded in either order (as well as the case where only one is
installed in a given database).

Idempotent: running it a second time matches zero rows.
