FR-6: Batch Description Handling

• If a single message has multiple image attachments, the relay generates a description for each
• The client receives an array of descriptions (one per attachment)
• Each description is rendered as a separate special bubble
• The bubbles are visually grouped: minimal vertical spacing (e.g., 4px instead of 10px) and/or a subtle left border connecting them

FR-7: User Toggle

• A setting show_image_descriptions (boolean, default: true) is added to config.json
• When false, image description bubbles are hidden entirely
• Non-image attachments still show generic placeholders regardless of this setting
• The toggle is accessible from the system menu (Start+Select → Settings)
