Add meta-store routing for topsql deltalake sink

[zeminzhou]

Summary

• add meta_store_addr to topsql_data_deltalake sink config
• resolve keyspace metadata from meta-store and cache org and cluster routing info
• write TopSQL DeltaLake data under org={org}/cluster={cluster} path segments when keyspace metadata is available
• keep the existing path layout as fallback when keyspace metadata cannot be resolved

Testing

• cargo check
• cargo test --lib common::meta_store::tests::resolve_keyspace_uses_tenant_as_org_id_and_caches_result -- --exact
• cargo test --lib build_table_path -- --nocapture
