Add decorative flourish to bottom of sidebar

Added asterism (⁂) at bottom of sidebar menu with:
- Centered placement with elegant spacing
- Border separator above
- Subtle opacity (0.6) for refined appearance
- Letter spacing for visual balance
- Matches the classical typography aesthetic

Provides a elegant finishing touch to the sidebar navigation.
