Add Openfort signer guide for Smart Accounts Kit

[joalavedra]

Description

Adds a "Use Openfort with MetaMask Smart Accounts" guide to the Configure signers section of the Smart Accounts Kit docs, following the structure of the existing Privy and Dynamic guides.

Openfort provides embedded wallets with social, email, and passkey sign-in via the @openfort/react SDK. Configured with accountType: AccountTypeEnum.EOA, the embedded wallet is an EOA that works as a smart account signer through the standard Wagmi Wallet Client — step 3 (toMetaMaskSmartAccount) is identical to the Privy and Dynamic guides.

Changes:

• New page smart-accounts-kit/guides/smart-accounts/signers/openfort.md (and the same page in gator_versioned_docs/version-1.6.0/, since the existing signer guides are identical in both).
• Adds Openfort to the signers index card list and keywords (both versions).
• Adds the sidebar entry in gator-sidebar.js and gator_versioned_sidebars/version-1.6.0-sidebars.json.

Code samples are written against current SDK versions (@openfort/react@1.1.1, wagmi 3.x, viem 2.x) and verified against working integrations. Prettier passes on all changed files.

Disclosure: I'm a founder at Openfort and happy to keep this guide up to date as the SDK evolves.

Overview
Adds Openfort to the Smart Accounts Kit Configure signers docs so developers can wire Openfort’s embedded EOA wallet into MetaMask Smart Accounts the same way as Privy and Dynamic.

A new how-to page (openfort.md) covers installing @openfort/react, setting up OpenfortProvider with OpenfortWagmiBridge and accountType: AccountTypeEnum.EOA, and creating the smart account via Wagmi’s walletClient and toMetaMaskSmartAccount. The same page is duplicated under gator_versioned_docs/version-1.6.0/ to match other signer guides.

Navigation and discovery are updated in gator-sidebar.js, version-1.6.0-sidebars.json, and both signers index.mdx files (Openfort card plus openfort in frontmatter keywords). No vercel.json redirects are required because this is a new route only.

Can you link to the configuration docs? The doc points to overview.

You can keep the sentence to be

`See [Openfort's documentation](link to configuration docs) for an advanced configuration.

Done — updated both copies of the guide to link to the React UI configuration page (https://www.openfort.io/docs/products/embedded-wallet/react/ui/configuration), which covers login methods, wallet recovery, and appearance/customization, instead of the docs overview. Pushed in 1b7a8b9.
