Introduces the concept of image thumbnails in chat, prior to this we uploaded and used full size chat images within channels and direct messages. The following changes are covered: - Post processing of image uploads to create the thumbnail within Chat::MessageProcessor - Extract responsive image ratios into CookedProcessorMixin (used for creating upload variations) - Add thumbnail to upload serializer from plugin.rb - Convert chat upload template to glimmer component using .gjs format - Use thumbnail image within chat upload component (stores full size img in orig-src data attribute) - Old uploads which don't have thumbnails will fallback to full size images in channels/DMs - Update Magnific lightbox to use full size image when clicked - Update Glimmer lightbox to use full size image (enables zooming for chat images)
