Add PhotoReducer to Photo Editing and Management (Web)

[eviloria01]

Adds PhotoReducer under Photo Editing and Management → Web, next to miniPaint (same fully-in-browser model).

Why it fits this list:

• Runs 100% client-side: image codecs (MozJPEG, libwebp, libavif, oxipng) compiled to WebAssembly. Photos are never transmitted to any server — there is no upload endpoint at all.
• No account, no tracking-based business model, no watermarks, no file limits.
• Covers the most privacy-sensitive image task people do online: compressing ID/passport-style photos and scanned documents to the exact file size that government portals and application forms demand (e.g. "under 100 KB").
• Clear privacy policy; available in English, Spanish and German.
