applyMissingMigrations ran the entire migration SQL as one transaction, which rolled back all changes when any statement failed (e.g. adding a NOT NULL column to a non-empty table). Replaced with prisma db push which compares the schema and applies only what's needed. Also added support for importing .sql files (not just .zip) in auto-import.
