[PR] [python][daft] Validate BLOB descriptor parsing [paimon]

QuakeWang opened a new pull request, #8462:
URL: https://github.com/apache/paimon/pull/8462

   ### Purpose
   
   Daft BLOB File conversion parsed serialized BlobDescriptor bytes manually. That bypassed the shared descriptor validation, so malformed bytes could leak low-level parsing errors, and descriptors with unsupported versions or invalid magic could be accepted.
   
   This PR reuses `BlobDescriptor.deserialize` in the Daft conversion path and adds regression coverage for malformed descriptors while preserving normal descriptor-to-File conversion behavior.
   
   ### Tests
   
     - `python -m pytest paimon-python/pypaimon/tests/daft/daft_blob_test.py -q`
     - `python -m pytest paimon-python/pypaimon/tests/daft/daft_blob_read_test.py -q`
