fix: landing page user test fixes (#162)

- Add VueQueryPlugin to landing main.ts (wagmi/vue requires it)
- Add Vite proxy for /api/graphql → ponder:42069/graphql
- Replace axios with native fetch in WalletCard.vue
- Add navigateTo() for CTA buttons (uses VITE_APP_URL env)
- Load contract addresses from bootstrap in landing entrypoint
- Add via_ir to foundry.toml (OptimizerV3Push3 stack-too-deep)
- Add VITE_APP_URL env to docker-compose landing service

Fixes: blank landing pages, broken LiveStats, missing CTA links,
missing contract addresses in footer
