Finalize footer layout and footnote placement

- Remove duplicate footnote 5 from left side (was appearing twice)
- Keep footnote 5 only in deviations section (right column) where it belongs
- Move literature reference "Formeln aus:" from right to left column
- Place reference after footnote 4 with horizontal separator
- This balances text distribution between both footer columns
- Left column: formulas 1-4 and literature reference
- Right column: only deviations from the article's formulas
