Fixes usability issues in ClickHouse Play UI, including pixel-perfect rendering on iPad and consistent progress indication after queries.

Why it matters

The update resolves two problems: the UI on iPad was not pixel-perfect due to unintended border radius and margin styles, and the progress indicator failed to display after the first query execution. These fixes improve the user experience by providing a visually accurate interface and reliable feedback during query execution.

How to use it

These fixes are applied automatically in the updated ClickHouse Play UI. Users do not need to take additional steps; the improvements will be visible when accessing the Play UI on an iPad or when running queries that show progress.
