🐛 app: avoid chain mismatch on bridge transfer

[dieguezguille]

Summary by CodeRabbit

• Bug Fixes
  • Fixed chain mismatch during bridge transfers: the app now explicitly switches to the transfer's source network and ensures non-native token transfers are submitted and confirmed on the correct blockchain, preventing confirmation failures and improving transfer reliability.

Walkthrough

Explicitly switch the wagmi client to the source chain before submitting a bridge transfer; for non-native ERC-20 transfers include chainId: source.chain on the transfer write and use the same chainId when waiting for the transaction receipt to avoid chain mismatch.
