Improved Column Sorting

[uozalp]

Problem
Currently, sorting columns requires memorizing keyboard shortcuts (e.g., shift+ for specific columns). This is not user-friendly, especially for tables with many columns where it's difficult to remember which key corresponds to which column.

Solution
Implemented a more intuitive column sorting workflow:

• Navigate through columns: Use Shift+Left / Shift+Right arrow keys to cycle through table columns
• Visual feedback: The currently selected column is displayed in bold text
• Sort the selected column: Press Shift+O to sort by the selected column (toggles between ascending/descending)

Benefits

• Discoverable: Users can see which column will be sorted before triggering the sort action
• Intuitive: Arrow keys provide a natural way to navigate between columns
• No memorization needed: No need to remember column-specific keyboard shortcuts
• Visual feedback: Bold text clearly indicates the currently selected column

This looks like a good approach as a keyboard-only compliment to #3632 👍
