Fix and reimplement: Expand cell height if there is only one row (Original #537, Revert #548)

[natalyjazzviolin]

Closes https://github.com/ClickHouse/control-plane/issues/12806

Why

If you run a command like show create table example_table, the row does not expand to show the full create table command.

What

This reverts PR #537 and fixes a syntax bug. It expands the row to the full height of the content:

To reproduce:

CREATE TABLE random_user_events (
    user_id UInt32,
    event_time DateTime,
    event_type Enum8('click' = 1, 'view' = 2, 'purchase' = 3),
    item_id String,
    price Decimal(10,2),
    quantity UInt16
) ENGINE = MergeTree()
ORDER BY (user_id, event_time)
PARTITION BY toYYYYMM(event_time)
SETTINGS index_granularity = 8192;

show create table random_user_events;
