Update DONE.md with Real-ESRGAN setup and window resize fix

Resolved issue where window would resize itself based on dynamic content
like progress bars and queue updates. Window now maintains the size that
the user sets, regardless of content changes.

**Problem:**
- When progress bars updated or queue content changed, the window would
  automatically resize to fit the new content MinSize
- This caused the window to get larger or smaller unexpectedly
- User-set window size was not being preserved

**Solution:**
- Modified setContent() to capture current window size before setting new content
- Restore the window size after SetContent() completes
- This prevents Fyne from auto-resizing based on content MinSize changes
- Window only resizes when user manually drags edges or maximizes

**Impact:**
- Window maintains stable size through all content changes
- Progress bars, queue updates, and module switches no longer trigger resize
- User retains full control of window size via manual resize/maximize
- Improves professional appearance and user experience
