### What problem does this PR solve?
Issue Number: DORIS-29461
Related PR: None
Problem Summary: Plugin-driven Hive catalogs accepted incomplete HDFS HA
properties during CREATE and ALTER. For example, a catalog with
`dfs.nameservices=ns1` but no `dfs.ha.namenodes.ns1`, or with an empty
nameservice list, could be persisted successfully and only fail when the first
external table accessed storage. The DDL validation path now binds Hive storage
properties before persisting the catalog, and HDFS HA validation rejects empty
nameservice entries and validates the required NameNode, RPC address, and
failover provider properties. The behavior is covered by FE unit tests and an
external regression suite.
### Release note
Hive Catalog CREATE and ALTER now reject incomplete HDFS HA configurations
during DDL validation.
### Check List (For Author)
- Test: Unit Test / Regression test
- FE unit tests: `PluginDrivenExternalCatalogConcurrencyTest`,
`HdfsPropertiesTest`
- External regression:
`external_table_p0/hive/test_hive_ha_catalog_validation`
- FE build and Checkstyle passed
- Behavior changed: Yes (invalid Hive HDFS HA configurations fail during
CREATE/ALTER instead of being deferred until storage access)
- Does this need documentation: No
