Fix UI scaling for small laptop screens (1280x768+)

Reduces default window size from 1280x800 to 1200x700 to fit on 1280x768 laptop screens. Reduces all hardcoded MinSize values for professional cross-resolution support:
- Window default: 1200x700 (was 1280x800)
- Log scroll: 600x350 (was 700x450)
- Deinterlace preview: 640x360 (was 800x450)
- Contact sheet viewer: 700x600 with scroll (was 900x700)
- Contact sheet image: 640x480 (was 800x600)
- Filters settings: 350x400 (was 400x600)
- Upscale settings: 400x400 (was 450x600)

All content uses scrollable containers for proper scaling. Window is resizable and can be maximized via window manager controls.
