🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Configure an administrator client for both grant examples.

The shared pubnub instance at lines 3–7 has no secretKey. Both new grant calls use that instance, so the examples cannot issue grants as written. Show a server-side instance configured with a valid keyset and a secret from secure configuration. Keep the secret out of client code. (pubnub.com)

Review comment at @docs-snippets/access-manager.ts at line 239:
Update both grantToken calls to use a server-side PubNub client configured with
the valid keyset and a secret loaded from secure configuration; do not add the
secret to client-side code. Keep the shared client unchanged for non-grant
examples.

Do not log the granted token.

The token grants access to list all channel and UUID metadata for its 15-minute lifetime. If application logs are exposed, logging the token exposes that credential. Log a success message instead, and pass the token directly to the code that needs it. (pubnub.com)

Review comment at @docs-snippets/access-manager.ts at line 247:
Replace the token-bearing console.log in the grant flow with a success message
that does not expose the credential, and continue passing the token directly to
the code that needs it.
