Fix issue #142 Footer Theme Inconsistency in Light Mode

[AribaRazi]

Description

The footer remained dark in light mode due to hardcoded dark theme utility classes applied directly to the footer element. This caused inconsistency in the UI when switching between light and dark themes.

Expected Behavior

• Footer should adapt correctly to both light and dark themes.
• Background, text, and border colors should respond dynamically to theme changes.

Current Behavior

• Navbar and other sections switch themes correctly.
• Footer remained dark even in light mode.

Changes Made

• Removed hardcoded dark background and border utility classes from the footer element.
• Replaced the existing footer class setup with a cleaner reusable footer class.
• Allowed the footer to inherit styling from the existing global theme system instead of forcing dark mode styles.

Result

• Footer now switches correctly between light and dark themes.
• Theme consistency is maintained across the entire website.
