Description
### Apache Iceberg version
1.10.0 (latest release)
### Query engine
None
### Please describe the bug 🐞
In the `HiveCatalog` implementation the Catalog name is ignored. For example in the `tableExists` method there is the following code:
`Table table = clients.run(client -> client.getTable(database, tableName));`
If the HiveCatalog used the Catalog name provided then the code would be:
`Table table = clients.run(client -> client.getTable(name, database, tableName));`
This change reflects that IMetaStoreClient code has two versions of the getTable method, one of which takes a Catalog name. Apologies if this is a duplicate issue, or there is a documented reason why Catalog names are not supported in HiveCatalog.
Raised as a bug rather than a feature request as the API takes a Catalog name so the expectation is that it will use it as expected.

Contributor guide
Research direction
Start in the HiveCatalog implementation at the tableExists method and compare its getTable call with the two IMetaStoreClient signatures described in the issue. Trace how the Catalog name is supplied there, then verify that the catalog-aware lookup is used and that the existing table-existence behavior remains correct.
