Add React + Openfort wallet example

[joalavedra]

What

Adds examples/react-openfort, a runnable example showing how to supply GHO on the Aave v4 Core Hub from an Openfort embedded wallet.

Openfort React is built on wagmi + viem, so the connected embedded wallet is a standard viem WalletClient. The example signs Aave transactions through the existing @aave/react/viem adapter, mirroring the structure of examples/react-connectkit. Auth and wallet creation/recovery are handled by the prebuilt OpenfortButton modal.

Files

Same layout as the sibling React examples:

• src/main.tsx — WagmiProvider → OpenfortWagmiBridge → OpenfortProvider → AaveProvider, using getDefaultConfig from @openfort/react/wagmi
• src/App.tsx — OpenfortButton for sign-in; renders the form once wagmi reports a connected wallet client
• src/SupplyForm.tsx — useSupply + useSendTransaction(walletClient) from @aave/react/viem
• src/client.ts, index.html, tsconfig.json, vite.config.ts, .env.example, public/aave.svg

Notes

• Requires VITE_OPENFORT_PUBLISHABLE_KEY and VITE_SHIELD_PUBLISHABLE_KEY (see .env.example and README).
• The supply handler targets the current @aave/react@next ExecutionPlan shape (Erc20Approval with byTransaction), matching the useSupply docstring in the SDK. The committed react-connectkit/react-privy/react-thirdweb examples still use the older Erc20ApprovalRequired/transaction member and no longer type-check against the current next tag — happy to update those in this PR or a follow-up if useful.

Verified locally: tsc --noEmit passes and vite build succeeds.
