Pull request overview

This PR introduces a new isPending prop across several UI components (Alert, Button, ButtonIcon, Table, TableRoot) to align with React Aria naming, while keeping the existing loading prop as a deprecated alias. It also updates styling hooks and documentation/stories to use the new naming.

Changes:

• Add isPending?: boolean to public component props and refactor internal Table pagination state from loading to isPending.
• Update CSS selectors from data-loading to data-ispending and update component implementations to set/consume the new data attribute.
• Update stories, docs-ui content, and add a changeset documenting the deprecation and migration.
