Address review feedback on no-permit fallback implementation

[Copilot]

Addresses three review comments on the EVM→Alfredpay no-permit fallback path.

• Narrow nonces() error handling – Catch only ContractFunctionExecutionError (contract revert) when probing EIP-2612 support. Network/transport errors now propagate for retry instead of silently falling back to the no-permit flow.

• Validate user-submitted tx hashes – waitForUserHash now verifies receipt.from matches state.walletAddress, preventing unrelated successful tx hashes from advancing the ramp.

• Dedicated no-permit phase messages – Added squidRouterNoPermitApprove, squidRouterNoPermitSwap, squidRouterNoPermitTransfer i18n keys with accurate UX copy (approve/swap/transfer) instead of reusing the permit authorization message.

// Before: any error silently falls back
} catch {
  userNonce = null;
}

// After: only contract-level reverts indicate missing permit support
} catch (error) {
  if (error instanceof ContractFunctionExecutionError) {
    userNonce = null;
  } else {
    throw error;
  }
}
