### What problem does this PR solve?
An external table can have incomplete owner references after metadata
recovery. When materialized-view rewrite is enabled, `CollectRelation`
constructs a `BaseTableInfo` from that table and aborts the entire query
because the database is null.
This change restores the catalog and database references before publishing a
registered external table. It also skips optional MTMV candidate collection
when an already-cached table still has incomplete owner metadata, so the
optimization cannot fail an otherwise valid query.
Related issue: #58441
### Test
- Added a unit test that verifies table registration restores both owner
references and permits `BaseTableInfo` construction.
- Added a unit test that verifies MTMV candidate collection does not fail a
query when owner metadata is incomplete.
- Ran `ExternalDatabaseTest` and `CollectRelationTest`: 35 tests passed, 0
failures.
- FE Checkstyle passed as part of the FE unit-test build.
### Release note
