perf(bundle): lazy-load emoji-mart picker (defer ~82 KB gzip from first paint)

@emoji-mart/data (~430 KB / ~82 KB gzip) was pulled into the initial load by three always-mounted views (catalog custom-prefix, nick-icon, chat-input emoji selector) importing it statically. Add LazyEmojiPicker — a Suspense wrapper that dynamically imports the data + Picker on first open — and use it in those three sites.

Verified via the build manifest: the entry chunk no longer imports vendor-emoji statically or dynamically; vendor-emoji is now a dynamicImport of src/index.tsx, loaded on first picker open. No behaviour change. typecheck 0, tests 545/545.
