Skip files outside partition structure in hive-partitioned listing tables

When a hive-partitioned listing table contains files in the root
directory (not inside any partition_col=value/ path), these files
have no partition values. Previously they were included with empty
partition_values, causing "Unable to get field named" errors when
queries reference partition columns.

Now try_into_partitioned_file returns None for files that don't
match the partition structure, and the caller skips them.
