MemeWarzone wallet connection upgrade

This package replaces the old hard-coded wallet modal with a 2026-style EVM wallet flow:

• Detects EIP-6963 wallet providers and legacy injected providers.
• Lists only detected wallets in the connect modal.
• Keeps a link to trusted EVM wallet directories when nothing is detected.
• Uses eth_accounts for hydration and eth_requestAccounts only after the user selects a wallet.
• Keeps your existing ethers provider/signer API, so existing launchpad code should continue to work.
• Adds no new npm dependencies.

Files to copy

Copy these into the repo, preserving paths:

• frontend/src/hooks/useWallet.ts
• frontend/src/contexts/WalletContext.tsx
• frontend/src/components/wallet/ConnectWalletModal.tsx

Patch TopBar

From the repository root, after copying the files above, run:

node apply-wallet-connection-patch.mjs

The patch script updates frontend/src/components/TopBar.tsx by:

1. removing the inline createPortal wallet modal,
2. removing the old WalletType/toast modal handler,
3. importing ConnectWalletModal, and
4. rendering <ConnectWalletModal open={walletModalOpen} onOpenChange={setWalletModalOpen} />.

If the script says TopBar.tsx did not change, make these manual edits:

import { useWallet } from "@/contexts/WalletContext";
import { ConnectWalletModal } from "@/components/wallet/ConnectWalletModal";

Remove the old handleWalletSelect function and replace the entire old {/* Wallet selection modal */} ... createPortal(..., document.body)} block with:

{/* Wallet selection modal */}
<ConnectWalletModal open={walletModalOpen} onOpenChange={setWalletModalOpen} />
