Bring the Rust client up to date with the latest Fluss 1.x server API: - Sync `fluss_api.proto` with the 1.x schema (new/renamed fields such as `rack`, `filter_predicate`, `remote_data_dir`, `PbLookupReqForBucket.keys`, `ScanKvResponse.records`, and the `ignore_if_not_exists` partition flag). - Register the new API keys in `api_key.rs`. - Add RPC message wrappers for the new admin operations: alter table/database, cluster config describe/alter, table stats, KV snapshot listing/metadata and lease acquire/release/drop, lake snapshot, ACL create/list/drop, server tags, rebalance trigger/progress/cancel, producer offset register/get/delete, cluster health, remote log manifests, and KV scan. - Expose all of the above as methods on `FlussAdmin`. - Adapt existing message wrappers and conversions to the new field shapes.
