Replace YouTube iframe embeds with clickable thumbnails (#1474 )

* Initial plan * Replace YouTube iframe with clickable thumbnail - Changed YouTube embed URL from embed format to watch format - Added ThumbnailUrl property to YouTubeVideoEmbedProjection using YouTube's standard thumbnail URL - Updated MessageGroupTemplate to render thumbnail image with link instead of iframe - Updated CSS to style thumbnail appropriately - Updated test to check for anchor link and thumbnail image instead of iframe Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com> * Address code review feedback - Use hqdefault.jpg instead of maxresdefault.jpg (guaranteed to exist for all videos) - Extract thumbnail URL logic to GetThumbnailUrl method for better testability Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com> * Simplify YouTube embed test to focus on data not structure - Remove checks for HTML structure (class names, nested elements) - Focus on verifying YouTube URL with correct video ID exists - Follow same pattern as other embed tests (Spotify, Twitch) Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com> * Fix data-canonical-url and improve test specificity - Use canonical (non-proxy) URL for data-canonical-url attribute - Extract thumbnailUrl to local variable to avoid duplicate calls - Update test to check for img with video ID in src, avoiding false positives - Test now verifies the actual thumbnail data rather than any link Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com> * Inline thumbnail URL logic directly into attributes - Remove GetThumbnailUrl method from YouTubeVideoEmbedProjection - Remove local variables from template - Put coalescing logic directly in src and data-canonical-url attributes Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Tyrrrz <1935960+Tyrrrz@users.noreply.github.com>
