Pull request overview

This PR fixes issue #5280 where horizontal scrollbars were appearing on some list pages. The fix involves adding CSS to hide horizontal scrollbars and refactoring duplicate cell width limiting code into a reusable utility method.

Changes:

• Added CSS class .no-horizontal-scrollbar to hide horizontal scrollbars on specific list views
• Created new utility method FXUtils.limitCellWidth() to consolidate duplicate code for binding cell widths to container widths
• Cleaned up redundant fully qualified class names in favor of shorter imported names
