feat(invoice+import): refresh facturi, detalii factura, fix duplicate CODMAT + rollback

- PL/SQL: handle duplicate CODMAT in nom_articole with MAX(id_articol)
- import_service: add explicit conn.rollback() on Oracle errors
- sync_service: auto-fix stale ERROR orders that exist in Oracle
- invoice_service: add data_act (invoice date) from vanzari table
- sync router: new POST /api/dashboard/refresh-invoices endpoint
- order detail: enrich with invoice data (serie, numar, data factura)
- dashboard: refresh invoices button (desktop + mobile icon)
- quick map modal: compact single-row layout, pre-populate existing mappings
- quick map: link on SKU column instead of CODMAT
