Pull Request Overview

Fix blob write/read paths when using blob-as-descriptor in Python.

• Propagate blob-as-descriptor option through writer and reader.
• Introduce UriReader abstraction and factory with caching; refactor BlobRef to read via UriReader.
• Update tests to cover descriptor-based blob IO and add UriReaderFactory tests.

File	Description
paimon-python/pypaimon/write/writer/data_writer.py	Pass blob_as_descriptor from options to FileIO.write_blob to control descriptor handling during writes.
paimon-python/pypaimon/common/core_options.py	Add FILE_BLOB_AS_DESCRIPTOR config key to toggle descriptor mode.
paimon-python/pypaimon/common/config.py	Add default cache size for UriReaderFactory.
paimon-python/pypaimon/common/uri_reader.py	New UriReader/Factory with HTTP/file readers and cached construction.
paimon-python/pypaimon/common/file_io.py	Add UriReaderFactory usage and change write_blob to support descriptor input; construct Blob via descriptors when needed.
paimon-python/pypaimon/read/split_read.py	Thread blob_as_descriptor option through to FormatBlobReader.
paimon-python/pypaimon/read/reader/format_blob_reader.py	Support returning descriptors or data based on flag; adapt iterator to construct Blob via FileIO.
paimon-python/pypaimon/table/row/blob.py	Refactor Blob* APIs to work with UriReader; BlobRef now reads via UriReader.
paimon-python/pypaimon/tests/blob_test.py	Update tests for new APIs and add end-to-end descriptor test; adjust calls to write_blob and readers.
paimon-python/pypaimon/tests/uri_reader_factory_test.py	New tests for UriReaderFactory behavior, caching, and basic IO.
