Summary of Changes

This PR improves the Joomla Administrator UI in the Fields list view (com_fields) by fixing how unassigned Field Groups are displayed.

Previously, if a field had no Field Group assigned, the "Field Group" column would appear blank in the admin table. This could confuse users or make it unclear whether the field was missing a group or had a configuration issue.

This fix updates the logic to:

• Detect when a field's group_title is empty
• Display JNONE ("None") instead of leaving the column blank
• Improve clarity for administrators managing custom fields

Testing Instructions

1. Go to the Joomla Administrator Panel.
2. Navigate to Users → Fields.
3. Create a new Field (or edit an existing one).
4. Leave the Field Group field unassigned.
5. Return to the Fields list.
6. Observe the "Field Group" column:
   • Fields assigned to a group show the group name ✅
   • Fields without a group now show "None" ✅

Actual result BEFORE applying this Pull Request

• Blank column for ungrouped fields.
• No clear indication that the field is intentionally ungrouped.

Expected result AFTER applying this Pull Request

• Clear "None" label is shown for unassigned field groups.
• Improved UX consistency and clarity for administrators.
