feat(clickpipes): expose streaming table definitions

[sdairs]

Streaming ClickPipe creates always sent a managed MergeTree destination with no way to select another engine or define partition, primary, and sorting keys. This adds shared --managed-table <true|false> and --table-definition-file <PATH|-> options to Kafka, Kinesis, object-storage, and Pub/Sub creates while preserving the existing managed MergeTree request when both are omitted.

The table-definition file is strictly deserialized into the typed Cloud API model, including engine.type, nullable versionColumnId, columnIds, partitionBy, primaryKey, and sortingKey. Unknown fields at the top level or inside engine, unknown engine variants, malformed JSON, and missing typed fields fail locally before an API request.

Validation:

• cargo fmt --all -- --check
• cargo clippy -p clickhousectl -- -D warnings
• cargo check -p clickhousectl --no-default-features
• cargo clippy -p clickhousectl --all-targets --no-default-features -- -D warnings
• cargo test -p clickhousectl

Closes #594
