fix(sync): detect deleted orders and invoices in ROA

Previously, orders deleted from Oracle (sters=1) remained as IMPORTED
in SQLite, and deleted invoices kept stale cache data. Now the refresh
button and sync cycle re-verify all imported orders against Oracle:
- Deleted orders → marked DELETED_IN_ROA with cleared id_comanda
- Deleted invoices → invoice cache fields cleared
- New status badge for DELETED_IN_ROA in dashboard and logs
