fix: update Freighter WalletConnect Explorer id to match live listing

The id previously hardcoded in WalletConnectModule's default featuredWalletIds
array no longer exists in the live WalletConnect Cloud Explorer, which is what
Reown AppKit resolves featuredWalletIds against. As a result, Freighter was
silently absent from the featured row of the WalletConnect modal for every
dApp using this kit. Swap in the current Explorer id for Freighter.
