fix: replace direct console.* calls with walletsLogger in wallets package

[devin-ai-integration]

Description

Part of the effort to make consoleLogLevel="silent" work across all SDK packages. Three direct console.* calls in the wallets package were bypassing the SdkLogger system, meaning they'd still appear even when a consumer sets consoleLogLevel="silent" on CrossmintProvider.

This replaces them with walletsLogger:

• ncs-iframe-manager.ts: 2× console.info → walletsLogger.info (iframe init lifecycle)
• wallet.ts: 1× console.warn → walletsLogger.warn (deprecated approveTransaction method)

Requested by: @xmint-guille
Link to Devin run

Test plan

• Existing tests cover wallets functionality; no behavioral change beyond log routing
• Reviewer should verify walletsLogger is initialized before NcsIframeManager.initialize() runs — if it isn't, SdkLogger falls back to raw console.* anyway, so logs would still leak in that edge case

Package updates

• @crossmint/wallets-sdk: patch — changeset added via .changeset/wallets-use-sdk-logger.md

Original prompt from Guille

we introduced the following change here to supress logs in our sdks:
https://github.com/Crossmint/crossmint-sdk/commit/27194e5751fd4bb3afb190550382760f978d7a20

i've tried this with the following code snippet, and I can still see logs once I'm logged in:
```ts
"use client";

import {
  CrossmintProvider,
  CrossmintAuthProvider,
  CrossmintWalletProvider,
  useAuth,
  useWallet,
} from "@crossmint/client-sdk-react-ui";

function WalletUser() {
  const { login, user } = useAuth();
  const { wallet, status } = useWallet();

  return (
    <div>
      {user == null ? (
        <button onClick={login}>Sign In</button>
      ) : (
        <p>
          Wallet: {wallet?.address} ({status})
        </p>
      )}
    </div>
  );
}

export default function Page() {
  return (
    <CrossmintProvider
      apiKey={process.env.NEXT_PUBLIC_CLIENT_API_KEY ?? ""}
      consoleLogLevel="silent"
    >
      <CrossmintAuthProvider>
        <CrossmintWalletProvider
          createOnLogin={{
            chain: "polygon-amoy",
            signer: { type: "email" },
          }}
        >
          <WalletUser />
        </CrossmintWalletProvider>
      </CrossmintAuthProvider>
    </CrossmintProvider>
  );
}

can you determine the issue and propose a PR in case it's feasible to maintain the silent logs flag in every part of our sdks?
