### What problem does this PR solve?
Related PR: #58166
Problem Summary:
When Observer FE receives edit logs from Master FE after a Hive insert
operation, it may miss adding new partitions to its partition values cache.
This happens because:
1. When inserting into a new partition, Master FE refreshes its cache and
gets the partition into its partition values cache
2. Master FE records the partition as MODIFIED (not NEW) in the edit log if
it already exists in HMS
3. Observer FE processes only newPartNames when updating partition values
cache, missing partitions marked as MODIFIED
Fix by merging both modifiedPartNames and newPartNames before adding to the
partition values cache, ensuring Observer FE stays synchronized with Master FE.
