fix: deduplicate tool icons and add missing icon mappings

7 icons were shared by multiple tools, now each tool has a unique icon:
- favicon: Globe -> AppWindow
- smart-crop: Focus -> Crosshair
- noise-removal: Sparkles -> AudioLines
- beautify: Sparkles -> ImagePlus
- red-eye-removal: Eye -> ScanEye
- color-palette: Palette -> Droplets
- transparency-fixer: Wand2 -> ShieldCheck
- pdf-to-image: FileOutput -> BookImage

2 icons were missing from the ICON_MAP (falling back to generic FileImage):
- Scaling (content-aware-resize)
- Laugh (meme-generator)
