PyIceberg commit not preserving Hive table properties

[bharos]

Apache Iceberg version

0.10.0 (latest release)

Please describe the bug 🐞

PyIceberg's Hive catalog loses HMS-specific table properties during table commits (e.g., during overwrite() operations).

When external systems or tools set HMS table parameters that are not managed by Iceberg (such as table_category from data contracts), these properties are lost when PyIceberg performs any table commit operation.

I think we're not merging the hive table's existing properties here :
