### Describe the issue this Pull Request addresses
Closes #18060
When records have null values in the precombine field, Hudi jobs fail with a
cryptic error message that makes it difficult for users to diagnose the root
cause:
```
org.apache.hudi.exception.HoodieException: Could not create payload for
class: org.apache.hudi.common.model.DefaultHoodieRecordPayload
Caused by: org.apache.hudi.exception.HoodieException: Ordering value is null
for record: ...
```
This error provides no actionable information about which field has the null
value, which record is problematic, or how to remediate the issue.
### Summary and Changelog
This change adds explicit null-checking with a clear, actionable error
message before attempting payload creation in `HoodieCreateRecordUtils.scala`.
**Changes:**
- Added null-check for ordering field values in
`HoodieCreateRecordUtils.scala`
- The new error message identifies:
- The specific precombine/ordering field that has a null value
- The record key to help locate the problematic record
- Suggested remediation options (fix data or use
`OverwriteWithLatestAvroPayload`)
- Added test cases in `TestHoodieCreateRecordUtils.scala` to verify the
improved error handling
**Example of improved error message:**
```
Precombine/ordering field 'ts' has null value for record key 'abc123'.
Please ensure all records have non-null values for the precombine field, or use
a payload class that doesn't require ordering (e.g.,
OverwriteWithLatestAvroPayload).
```
### Impact
No public API changes. This is a usability improvement that provides clearer
error messages when data quality issues occur during ingestion.
### Risk Level
low - The change only affects error handling and adds a null check before an
operation that would fail anyway. The behavior for valid data remains unchanged.
### Documentation Update
none - No new configs or features added. This is an error message
improvement.
