Stop executing AppImages during analysis, add screenshot lightbox and favicons

- fuse.rs: Replace Command::new(appimage_path) with 256KB binary scan for
  runtime detection - prevents apps like Affinity from launching on tile click
- fuse.rs: Read only 12 bytes for Type 2 magic check instead of entire file
- security.rs: Use find_squashfs_offset_for() instead of executing AppImages
  with --appimage-offset flag
- updater.rs: Read only first 1MB for update info instead of entire file
- detail_view.rs: Click screenshots to open in lightbox dialog
- detail_view.rs: Fetch favicons from Google favicon service for link rows
