Override to ensure proper table configuration for Fabric

Note: Fabric doesn't support table indexing - it automatically manages storage.

create_load_job​

def create_load_job(table: PreparedTableSchema,
                    file_path: str,
                    load_id: str,
                    restore: bool = False) -> LoadJob

Override to handle file loading - Fabric requires staging for parquet files

Fabric doesn't use ADBC for direct parquet loading. Instead, it requires staging storage (OneLake or Azure Blob) and uses COPY INTO for efficient bulk loading.
