optimize: fix JS heap memory errors and reduce bundle size

**Memory Fixes:**
- Increased Node.js heap size to 8GB for Netlify builds
- Added NODE_OPTIONS='--max-old-space-size=8192' to build command

**Dependency Optimization:**
- Pinned all "latest" dependencies to specific versions to prevent conflicts
- Fixed 6 duplicate versions of 'ox' library causing massive bloat
- @dynamic-labs/ethereum: latest -> 4.32.0
- viem: latest -> 2.37.6
- wagmi: latest -> 2.17.0

**Bundle Splitting:**
- Added manual chunk splitting in Vite config:
  - vendor.js (141KB) - React core
  - wallet.js (4.4MB) - Wallet/crypto libs
  - ui.js (259KB) - MUI components
  - main.js (1MB) - App code
- Reduced main bundle from 5.8MB to 1MB

**Build Performance:**
- Maintained 22s build time locally
- Should prevent "heap out of memory" errors on Netlify
