Bump viem/rainbowkit/react-query + fix Next.js SSR errors from new WalletConnect

[rin-st]

Summary

• Bump in example: viem 2.39.0 → 2.48.4, @rainbow-me/rainbowkit 2.2.9 → 2.2.10, @tanstack/react-query ^5.28.6 → ^5.100.9. Matching bumps in packages/burner-connector plus eslint/prettier dev deps.
• Fix ReferenceError: indexedDB is not defined thrown during SSR by WalletConnect's keyvaluestorage on createConfig → connector.setup(). ScaffoldETHProvider now next/dynamic-imports the real provider tree (ScaffoldETHProviderInner) with ssr: false; wagmiConfig drops ssr: true accordingly.
• Silence harmless Critical dependency: the request of a dependency is an expression webpack warning from ox/_esm/tempo/internal/virtualMasterPool.js (intentional await import(id) indirection) via webpack.ignoreWarnings in next.config.mjs.

Test plan

• pnpm install clean
• pnpm build (burner-connector tsc) succeeds
• pnpm dev in example/: no indexedDB/unhandledRejection in terminal, no Critical dependency warning
• Burner Wallet → connects, address shows
• WalletConnect → modal opens, pairing works
• MetaMask → connects, sign/send works
• Sign Message, Send Transaction, Send Calls (5792), Refetch Total Counter all work end-to-end
