Describe the subtask

Support view operations in Hive catalog and keep the implementation maintainable:

• Add and refine Hive catalog view CRUD behavior.
• Extract view logic from HiveCatalogOperations into HiveViewCatalogOperations via composition.
• Keep current behavior explicit by rejecting unsupported dialects with clear errors.
• Update and align tests for view create/load/alter/drop/list behavior.
