[PR] fix(arrow): map BLOB to LargeBinary [paimon-rust]

["JingsongLi (via GitHub)" <gi...@apache.org>]

   BLOB values can exceed Arrow Binary 32-bit offsets and PyPaimon already exposes BLOB as LargeBinary. This change maps scalar and nested BLOB values to LargeBinary across format readers/writers, descriptor resolution, data evolution, residuals, variant shredding, and DataFusion BLOB functions. BINARY and VARBINARY remain Binary.
   
   This is required by apache/paimon#9954 so native reads return the requested Python schema directly.
   
   Tests:
   - cargo test -p paimon --lib blob (129 passed; two sandbox-only REST token tests excluded)
   - cargo test -p paimon --lib table::data_evolution_reader::tests:: (75 passed)
   - cargo test -p paimon-datafusion --test blob_tests (25 passed)
   - cargo test -p paimon-datafusion --test blob_descriptor_functions (4 passed)
   - Python binding tests/test_read.py (81 passed)
