Update EW iOS Documentation

Update EW iOS Documentation to v12

---

Note

Low Risk
Documentation-only changes with no application or SDK runtime code; risk is limited to broken links or outdated examples misleading integrators.

Overview
Updates Embedded Wallets iOS SDK docs from v10/v11 patterns to v12 (12.0.1), including the migration guide, get-started flow, advanced/usage pages, Solana/EVM connect guides, and quickstart references.

API and terminology renames are applied consistently: W3AInitParams → Web3AuthOptions, login → connectTo with LoginParams/AuthConnection, web3Auth.state → web3AuthResponse, private key helpers renamed, and Wallet Services launchWalletServices → showWalletUI with chains configured in options instead of per-call chainConfig.

Integration guidance changes include async try await Web3Auth(options:) (no separate initialize()), removal of setResultUrl/URL callback setup, default session length documented as 30 days, and new/expanded coverage for authConnectionConfig, chains, walletServicesConfig, and SFA via idToken.

Navigation and links: sidebar entries and Vercel redirects point old paths (login, launch-wallet-services, legacy private-key URLs) to the new pages; the iOS migration index targets v12 (Android table row corrected to v9). Link checker ignores Tenderly URLs.
