Fix print preview paper dimensions and cleanup redundant CSS files

- Change print preview to landscape orientation (11" x 8.5")
- Fix paper div to render at exact 1056x816 pixels
- Add 48px padding (0.5 inches) directly to paper div
- Remove CSS file redundancy: deleted styles.css.backup, styles/base.css, styles/default.css
- Improve modal sizing to accommodate paper dimensions
