Closes #2372
# Rationale for this change
PyArrow's pa.uuid() type creates Python Arrow metadata that differs from
Java Arrow's UUID metadata, causing incompatibility with Spark. Python and Rust
Arrow implementations don't recognize Java's UUID metadata.
- Change UUIDType Arrow schema conversion from pa.uuid() to pa.binary(16)
- Add integration test verifying UUID round-trip between PyIceberg and Spark
- Update existing tests to expect binary(16) instead of pa.uuid()
- Bump Iceberg version to 1.10.1 which includes Java-side UUID fix
## Are these changes tested?
