fix: migration 028 handles missing created_by column

The migration was using SELECT * which fails when migrating databases
that predate the created_by column (34 columns vs 35). Now explicitly
lists columns and provides empty default for created_by if missing.

Also fixes missed Wisp→Ephemeral rename in multirepo_test.go.
