Show inline image previews for binary files

Add inline image preview support for binary image files in diffs and the file viewer. Frontend: new CSS rules for diff/viewer image panels and macOS window radius, JS templates to render base64 image previews and wire previewMime/previewBase64 into rendering flow, plus applyPlatformChrome to set platform-specific chrome. Backend (Tauri): add base64 and ico deps and expose image preview data (mime + base64) on GitFileDiff and LocalRepoFile; implement mime detection, size-limited preview generation (5MB), .ico → PNG extraction, and integration into get_file_diff and local_repo_file to return previews when available. Also updates icon asset.
