Add underline styling to video titles for accessibility

[Copilot]

Video titles in the home page Videos section lacked visual link affordances (underline), making them indistinguishable from plain text for low vision users.

Changes

• Added underline class to video title links in videogallery.svelte
• Links maintain default text color while providing clear visual affordance through underline

Before:

<a class="text-xl" href={video.link}>

After:

<a class="text-xl underline" href={video.link}>

Screenshot

Links now display with underline, meeting WCAG requirements for visual link identification.

@copilot I don't want the text to be cyan, just underlined in general

Updated in commit 20c9222. The video links now have underline only, without the cyan color.
