refactor: replace delete dialog with inline confirmation

Replace popup modal with inline confirmation UI:
- When delete is clicked, show red trash icon with 'Confirm?' text
- Clicking red trash icon again confirms deletion
- Confirmation appears to left of three-dot menu
- Click outside or reopen menu cancels confirmation
- Remove ConfirmDialog component dependency
