Harden migration: transaction, chunking, lossy-down doc, data-preservation test

Browse Source 
- Wrap the data copy in DB::transaction (FULLTEXT ALTER stays outside)
- Switch to chunkById(500) so the migration scales
- Document down() as irreversible for non-default-locale translations
- Add test_existing_documents_data_is_copied_to_translations to cover
  the data copy itself (the only previously-untested behavior)
- Drop unused Migrator import in DocumentMigrationTest
- Also restore title index in down() so up() can be re-run cleanly
