"""Rename musehub_pack_index → musehub_mpack_index.

The ORM model has been MusehubMPackIndex since issue #63; the table name is
now aligned to match.  All column renames (object_id→entity_id, pack_id→mpack_id)
and the entity_type addition were done in 0063.  This migration only renames
the table and its index.
