React SDK: Lazy-load DynamicWalletProvider and FarcasterProvider to reduce bundle size

[jmderby]

Description

• Lazy-load DynamicWalletProvider in CrossmintAuthProvider — @dynamic-labs/ethereum, @dynamic-labs/solana,
  @dynamic-labs/sui, and @dynamic-labs/sdk-react-core are now deferred behind React.lazy() and only loaded when
  loginMethods includes a web3* method
• Lazy-load FarcasterProvider and FarcasterSignIn in AuthForm — @farcaster/auth-kit is now deferred and
  only loaded when loginMethods includes farcaster
• Follows the same pattern already used in EmbeddedCheckoutV3IFrame for CryptoWalletConnectionHandler

Motivation

Crossmint auth is primarily used in demos and staging apps. Consumers using other packages shouldn't pay the cost of loading the full auth dependency tree (Dynamic Labs, Farcaster) when they don't use those features.

Test plan

• tested app
• tested login methods
