Replace themes with 50 retro-futuristic single-column themes

- Removed previous multi-layout themes
- Generated 50 new retro/retro-futuristic themes with:
  - Single column layout only
  - Minimum 1200px width for modern displays
  - Retro computing aesthetics (terminal, CRT, synthwave, etc.)
  - Various visual effects: scanlines, CRT, grid, dots, terminal
  - Monospace typography throughout

- Theme palettes include:
  - Classic terminal green
  - Amber CRT monitors
  - Synthwave purple/pink
  - Matrix green
  - DOS blue/white
  - Cyberpunk neon
  - And more retro color schemes

- Updated index.html with retro-themed gallery interface
- All themes W3C CSS validated
- Proper font licensing maintained
- Screenshot previews for all themes
