Hudi Partition Key Generator for Decimal and Timestamp Field is buggy

!image.png|width=2357,height=1535!

As can be seen, the when performing writes, decimal fields are not correct on the filesystem path, but is correct in the data file.

This will be problematic for Trino as partition values are generated from Path values instead of data file.

Start by tracing Hudi's Partition Key Generator during writes, comparing how decimal and timestamp values are represented in filesystem paths versus data files. Reproduce the issue and check the resulting paths, then verify that Trino can derive the intended partition values from those paths.
