feat: major UI redesign - vertical layout

New layout structure:
1. Top row: Cache Source | Output Location (side by side)
   - More vertical space allocated
   - Both sections have equal width

2. Middle: Available Icons (full width)
   - Takes remaining vertical space
   - Expands to fill available area

3. Bottom: Action buttons
   - Select All / Select None on left
   - Open Output Folder in middle
   - Start Extracting Icons (main action) on right

Removed:
- Export Settings box (hardcoded settings)
- EntropiaNexus.com box (already explained in top text)
- Splitter layout (now vertical flow)

Simplified, cleaner UI with all essential elements visible.
