Replace inline CSS styles with Bootstrap 5 utility classes across Spark Web UI Scala files. **Conversions:** - `display: flex; align-items: center` → `d-flex align-items-center` - `display: inline-block` / `display: 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 in webui.css) **Files changed (10):** - UIUtils.scala, PagedTable.scala, StagePage.scala, DriverLogPage.scala - ExecutorThreadDumpPage.scala, MasterPage.scala, 3 LogPage variants - webui.css (added cursor-pointer utility) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Replace float: right in webui.css with Bootstrap 5 float-end utility class. - Removed float: right from a.link and span.expand-details CSS rules - Added float-end class to 6 HTML elements across MasterPage, AllJobsPage, StageTable, UIUtils Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
