### What problem does this PR solve? Related to #67578 (partial A3). Flight SQL clients can obtain FlightInfo for GetTableTypes, but reading its ticket fails with UNIMPLEMENTED. GetTables also forwards only the first table_types entry to a service that treats only VIEW as a filter: [VIEW, BASE TABLE] loses base tables, while [BASE TABLE] or an unknown type can return excluded rows. Implement the type stream using the same Doris names as GetTables (BASE TABLE, SYSTEM VIEW and VIEW), sorted according to Flight SQL. Match the complete filter against the existing authorized listing before collecting optional schemas. Request only name/type metadata to avoid unused table statistics, and retain the session guard and Arrow buffer cleanup on failed sends. A type is the TABLE_TYPE that information_schema.tables reports for the object: table streams are VIEW, and external catalogs report their tables and views as BASE TABLE. The service lists every authorized object and the filter runs on that listing. Requested names match case-insensitively, and TABLE and SYSTEM TABLE, which Flight SQL calls commonly supported, select BASE TABLE and SYSTEM VIEW: the ADBC Flight SQL driver asks for `table` (Doris's own ADBC catalog lists a Doris source with `getObjects(..., {"table"})`), and JDBC tools ask for `TABLE`. Any other name matches only a type of that name, so UNKNOWN selects nothing. Because the filter now runs on the full listing, `FrontendServiceImpl.listTableStatus` refreshes a cloud follower's partition versions from the meta service only when UPDATE_TIME is requested, the one column that reads them. GetTables, which asks for names and types, never waits on those RPCs or is cut short when they fail, and information_schema.tables scans that do not read UPDATE_TIME skip the refresh too.

👣 Get Started
🧱 Architecture
Apache Doris supports both compute-storage coupled and compute-storage decoupled deployments. In decoupled mode, stateless compute groups run over shared object storage, so you can scale compute on demand and isolate workloads.
