### Purpose `sys.max_pt` only accepted `SparkTable`, so calling it on a format table failed with an `AssertionError`. Catalog-managed format table partitions also report a zero file count both before statistics are reported and when a partition is truly empty, so the existing `fileCount > 0` filter cannot tell them apart. Accept every Paimon `BaseTable`, and for format tables check partition candidates from largest to smallest with an exact partition-filtered scan, returning the first one that produces data. `FileStoreTable` keeps the metadata-only path. Null top-level partition values are ignored. ### Tests New cases in `PaimonFormatTableTest` cover catalog-managed data, empty registered partitions, empty filesystem directories, null partitions, and unpartitioned tables. -- This is an automated message from the Apache Git Service.
