Adds a `Map` cache inside `client/src/components/base/IconifyIcon.tsx` to memoize the result of `getIconData()` lookup logic across renders. This stops linear checking across multiple static icon bundles.

+## 2025-02-12 - IconifyIcon Lookups Uncached
+**Learning:** `client/src/components/base/IconifyIcon.tsx` resolves icons statically from multiple imported `@iconify-json` bundles but performs a linear lookup with `getIconData()` on every render without caching.
+**Action:** Add a simple `Map` cache inside `IconifyIcon.tsx` to memoize the result of `getIconData()` across renders.
