### What changes were proposed in this pull request? Replaces inline CSS styles with Bootstrap 5 utility classes across Spark Web UI Scala files, producing cleaner markup and smaller HTML output. **Conversions (10 files):** | Inline Style | BS5 Utility | |---|---| | `display: flex; align-items: center` | `d-flex align-items-center` | | `display: inline-block` / `inline` | `d-inline-block` / `d-inline` | | `vertical-align: bottom` / `middle` | `align-bottom` / `align-middle` | | `text-decoration: none` | `text-decoration-none` | | `white-space: nowrap` | `text-nowrap` | | `margin-right: 15px` | `me-3` | | `margin-bottom: 0` | `mb-0` | | `padding-right: 4px` | `pe-1` | | `overflow: auto; padding: 5px` | `overflow-auto p-1` | | `overflow: hidden; text-overflow: ellipsis` | `overflow-hidden text-truncate` | | `cursor: pointer` | `cursor-pointer` (new utility) | Styles with no BS5 equivalent (e.g., `width: 60px`, `height: 80vh`) are retained as inline styles. ### Why are the changes needed? Consistent use of BS5 utilities instead of inline styles aligns with the Bootstrap 5 migration (SPARK-55760). This makes the HTML cleaner, reduces inline style declarations, and makes visibility/layout inspectable via CSS classes. ### Does this PR introduce _any_ user-facing change? No. Visual appearance is identical. ### How was this patch tested? - `scalastyle` passes - `UIUtilsSuite` (8 tests) passes - Compilation verified for core and streaming modules ### Was this patch authored or co-authored using generative AI tooling? Yes, co-authored with GitHub Copilot. -- This is an automated message from the Apache Git Service.
