[PR] fix(python): close exhausted blob fallback readers [paimon]
discivigour opened a new pull request, #8622:

- preserve final reader cleanup through BlobFallbackBatchReader.close
- add coverage that verifies exhausted readers are closed as batches advance
## Testing

- python -m unittest pypaimon.tests.blob_test.BlobEndToEndTest pypaimon.tests.blob_table_test.DedicatedFormatWriterTest.test_update_blob_column pypaimon.tests.blob_table_test.DedicatedFormatWriterTest.test_array_blob_column_write_read_and_update
