feat: highlight config overrides in variable display

- Add original_value tracking to show what config changed
- Display 'original → config_value' format with arrow icon
- Highlight arrow and config value in yellow for visibility
- Show '(none)' when original value was empty
- Remove Origin column from display (redundant with arrow notation)
- Only show arrow when values actually differ
