Adds a space-key Quick Look preview to DSH deliverable cards. Hovering a card and pressing Space opens the native macOS QLPreviewPanel for the file, which covers docx, xlsx, pptx, pdf, images and media that the sidebar preview cannot render. The panel zooms out from the card's position, returns focus to the composer when closed, and exposes hover delay, focus-return and double-click behaviour in Settings > General.
