Fix Compare module layout to properly utilize window space

Resolved UI framing issues where metadata was crushed and not
taking available vertical space:

Layout improvements:
- Used container.NewBorder to make metadata areas expand properly
- Set minimum sizes for scroll containers (300x200)
- Removed outer VScroll - individual metadata areas now scroll
- Grid columns now properly fill available vertical space
- Instructions fixed at top, metadata expands to fill remaining space

Text wrapping fixes:
- Added fyne.TextWrapBreak to file labels
- Prevents long filenames from stretching the window horizontally
- Labels now wrap to multiple lines as needed

Architecture changes:
- Separated file headers (label + button) from content
- Each column uses Border layout: header at top, metadata fills center
- Metadata scroll containers have explicit minimum sizes
- Two-column grid properly distributes horizontal space

The layout now feels more modern with better space utilization
and smooth scrolling within the metadata panels.
