Resolves #3162

This PR adds support for featured wallet IDs in the WalletConnect (Reown AppKit) modal, allowing specific wallets to be promoted as recommended options. This enables Credit Wallet to appear as a recommended wallet for all Creditcoin chains.

Proposed Changes

• Added NEXT_PUBLIC_WALLET_CONNECT_FEATURED_WALLET_IDS environment variable to configure featured wallet IDs
• Updated blockchainInteraction.ts to parse and pass featured wallet IDs to the wallet connection configuration
• Modified Web3ModalProvider.tsx to use the featured wallet IDs from the feature configuration instead of an empty array
• Updated environment variable validator schema to include the new variable
• Updated documentation to reflect the migration from WalletConnect to Reown AppKit branding

Environment Variables

Added NEXT_PUBLIC_WALLET_CONNECT_FEATURED_WALLET_IDS to configure a list of featured wallet IDs that appear as recommended wallets in the "Connect your wallet" modal. This allows Credit Wallet to be promoted for Creditcoin chains by setting the appropriate wallet ID(s) in the environment configuration.

Breaking or Incompatible Changes

None. The new environment variable is optional and defaults to an empty array if not provided.

Additional Information

This change enables the promotion of Credit Wallet (or any other wallet) as a featured/recommended option in the wallet connection modal for Creditcoin chains. The wallet IDs can be obtained from WalletGuild.
