fix: enable dark mode support on Courses page

[kalyaniugale]

Description

This PR fixes the issue where the Courses page did not properly respond to the dark mode toggle in the navbar.
By defining the correct CSS variables for [data-theme='dark'], the page now automatically adapts when the theme is switched.

Fixes #581

Type of Change

• Bug fix (non-breaking change that fixes an issue)

Changes Made

• Updated courses.css dark theme block to include proper values for:
  • Background colors (--courses-bg-primary, --courses-bg-secondary, --courses-bg-tertiary)
  • Text colors (--courses-text-primary, --courses-text-secondary, --courses-text-muted)
  • Borders & shadows (--courses-border, --courses-shadow, etc.)
• Removed references to undefined --dark-* variables.
• Verified that existing var(--courses-*) references in components now switch styles correctly with the navbar toggle.

Dependencies

• No new dependencies added.
• No config changes required.
