Fix #2237: Insufficient contrast on hover state for links in tables in dark mode

[calebjubal]

Description

This pull request fixes the issue where table links in dark mode were not clearly visible when hovered. The color contrast was too low, making the text hard to read.

Changes Made

• Added a new SCSS variable for dark mode:

  

• Updated the link hover color in dark mode tables:

  

• And changed the default color of the table links in light mode for contrast:

  

• Replaced static color references with theme variables where applicable for consistency.

Screenshots

Testing

• Verified in both light and dark themes.

• Confirmed that hover color works as expected in dark mode.

• Checked that no other UI components or color variables were affected.

Thanks for the PR. I see that you have changed the color for prefers-color-scheme and the hover color in data-theme=dark. Both the changes need to be applied in both the places, so that all dark mode scenarios are covered. I have left inline comments for the same. Once that is fixed, I think we can merge this PR.
