⚡ Bolt: Optimize Iconify to dynamically load icons instead of static bundling

[sshahriazz]

💡 What: Refactored client/src/components/base/IconifyIcon.tsx to remove static imports of @iconify-json/* packages. It now passes the icon string directly to the @iconify/react <Icon> component, allowing for dynamic fetching.

🎯 Why: The codebase was previously importing over 10 entire icon set JSON objects directly into the JavaScript bundle. This caused massive bundle bloat and slow parsing times since thousands of unused icons were sent to the client.

📊 Impact: Drastically reduces Next.js First Load JS size. For example, the /auth/login route chunk dropped from ~8.96 MB down to ~1.24 MB, saving over 7 MB of parsed JSON data per page load.

🔬 Measurement: Verified by running pnpm --filter client build before and after to observe the Next.js static page bundle size output. Also verified UI renders properly via local dev Playwright script. Added learning to .jules/bolt.md.
