[PR] [python][ray] Honor partition overwrite in write_ray [paimon]

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

QuakeWang opened a new pull request, #8088:
URL: https://github.com/apache/paimon/pull/8088

   ### Purpose
   
   `TableWrite.write_ray()` previously did not carry builder-level overwrite partitions into the Ray datasink. As a result, `table.new_batch_write_builder().overwrite({...}).new_write().write_ray(...)` wrote through Ray without the configured partition overwrite contract, while `overwrite=True` only supported full-table overwrite.
   
   This PR carries the builder static partition into `TableWrite`, forwards it to `PaimonDatasink`, and applies the same overwrite partition on both Ray write tasks and the driver-side commit path.
   
   ### Tests
   
     - `python -m py_compile` on changed Python files
     - `pycodestyle` with project flake8 options on changed Python files
     - `pyflakes` on changed Python files
