### What problem does this PR solve? Issue Number: None Related PR: None Problem Summary: Flight SQL `GetDbSchemas` and `GetTables` restrict an omitted catalog to `internal`, hiding external catalog metadata. An explicitly empty catalog has the opposite problem: the underlying Thrift API treats it as an unrestricted search. Preserve an omitted catalog as an unrestricted search, keep named catalog filters, and return no matches for an empty catalog because every Doris database belongs to a catalog. Request database names without IDs to avoid materializing database objects when discovering metadata across catalogs. Existing user identity and privilege filtering remain in use. ### Release note Flight SQL schema and table discovery includes external catalogs when the catalog argument is omitted. An empty catalog argument returns no matches. ### Check List (For Author) - [x] Unit Test: 48 related FE tests passed, including 12 new parameterized cases that fail on the original implementation. Coverage includes schema/table discovery, both include-schema modes, same-named databases across catalogs, serialized array schemas, and names-only requests. - [x] Regression test: add raw Flight client coverage comparing external catalog metadata with SQL SHOW/DESC results. The framework and new Groovy suite compile; execution requires the external test environment and was not performed locally. - Behavior changed: Yes, omitted and empty catalog arguments follow Flight SQL semantics; explicit named filters retain their behavior. - Does this need documentation: No, this corrects protocol compatibility. -- This is an automated message from the Apache Git Service.
