feat(migration): suporte a upload de arquivos RAR, SQL e SQL.GZ

- Dockerfile: instala p7zip no Alpine para extração de RAR via 7z
- migration/routes.ts: detecta .rar, .sql.gz e .sql; extrai RAR com 7z,
  descomprime .gz com gunzip, analisa tabelas do dump SQL
- Migration.tsx: accept e hint atualizados para incluir RAR/SQL
