What

Adds an integration-test harness and tests for the 1.x admin surface:

  • Cargo.toml: integration_tests + fluss_v1 feature flags (the latter gates tests exercising APIs only on 1.x servers).
  • admin_extended.rs: end-to-end tests for the extended admin methods (ACLs, cluster configs, rebalance, server tags, producer offsets, KV snapshots, table stats).
  • admin_v1.rs: tests for the 1.x-only RPCs.
  • test_fluss.rs: wires the new test modules.

Tests tolerate UnsupportedVersion so the same suite runs green against both 0.9.x and 1.x server images.

Stack

Part 5/6, stacked on #631#630#629#628. All target main.

- Update fluss_api.proto with all 1.x message types (ACLs, KV snapshots,
  producer offsets, cluster config, rebalance, server tags, etc.)
- Add optional fields: rack, remote_data_dir, leader_epoch, agg_mode, etc.
- Register 24 new ApiKey variants (1023-1064) in api_key.rs
- Update build.rs prost bytes config for new proto fields
- Add None defaults in convert.rs and partition.rs
- Update pre-existing message wrappers that reference renamed proto fields /
  ApiKey variants so the crate still builds:
    * create_partition.rs: ignore_if_exists -> ignore_if_not_exists
    * get_latest_lake_snapshot.rs: ApiKey::GetLatestLakeSnapshot -> GetLakeSnapshot
    * list_databases.rs: populate new include_summary field
    * lookup.rs: PbLookupReqForBucket.key -> keys; new LookupRequest fields

Add 9 RPC message wrapper types:
- alter_database, alter_table (DDL operations)
- get_table_stats (table statistics)
- list_database_summaries (database listing with summaries)
- create_acls, list_acls, drop_acls (ACL management)
- describe_cluster_configs, alter_cluster_configs (cluster configuration)

Each wrapper follows the standard pattern: a request struct wrapping the
proto-generated type, implementing RequestBody (tying to ApiKey and ResponseBody),
WriteType, and ReadType.

Add message wrappers for the remaining 1.x RPC APIs:
- KV snapshot lifecycle: acquire/release/drop lease, list, metadata,
  latest snapshots, lake snapshot
- Server management: add/remove server tag, rebalance + progress +
  cancel, get cluster health, list remote log manifests
- Producer offsets: register/get/delete
- ScanKv (API 1061): full KV-table bucket scan request/response
Add 27 new admin methods to FlussAdmin:
- Database/table extensions: list_database_summaries, alter_database,
  alter_table, get_table_stats
- KV snapshot operations: get_latest_kv_snapshots,
  get_kv_snapshot_metadata, create_kv_snapshot_lease, get_lake_snapshot
- ACL management: create_acls, list_acls, drop_acls
- Cluster configuration: describe_cluster_configs, alter_cluster_configs
- Server management: add_server_tag, remove_server_tag, rebalance,
  list_rebalance_progress, cancel_rebalance
- Producer offsets: register_producer_offsets, get_producer_offsets,
  delete_producer_offsets
- Monitoring: get_cluster_health, list_remote_log_manifests
- KV snapshots: list_kv_snapshots, release_kv_snapshot_lease,
  drop_kv_snapshot_lease
