Fix mobile slide tables and thumbnails

 - Updated web and player container images to Node.js 26.12.1 to address the October 2026 security releases.
 
+### Fixed
+
+- Slide thumbnails and empty placeholders on Slides and playlist pages preserve the canvas aspect ratio and display the full image without cropping on smaller screens; standalone thumbnails are centered within their column.
+- Responsive tables keep descriptive text columns wide enough for multi-word lines on mobile, using horizontal scrolling instead of squeezing text into narrow columns.
