fix(migrate-db): preserve false-valued columns in SQLite to Postgres copy

GORM struct INSERT substitutes a column default tag for Go zero-values, so disabled rows (enable=false) silently re-enabled on the destination. Copy each batch through explicit per-column maps so every value is written verbatim. Adds a regression test.
