Description:
After upgrading from version 0.24.0 to 0.25.1, I've encountered an issue where the Produce button becomes disabled when trying to copy a message for production in KafkaHQ.

Steps to reproduce:

1. Upgrade AKHQ to version 0.25.1.
2. Copy a message in KafkaHQ to produce it.
3. Notice that the Produce button is disabled when the Value schema is populated.

Observations:

• No logs are displayed on the console indicating why the button is disabled.
• After adding some logging to the code for debugging, I observed the following error message: valueSchema is not allowed.

x(this, "validate", () => {
    const { error: t } = H.validate(this.state.formData, this.schema);
    if (!t)
        return null;
    console.log("log: " + t); // added the logging here
    const s = {};
    for (let a of t.details)
        s[a.path[0]] = a.message;
    return s;
});

• When hovering over the Value schema field, it appears to be stuck in a loading state with a constant loading pointer.
• The issue only occurs when using the Copy button on a message. However, if I directly click the Produce to topic button on a topic, everything works fine.

Expected behavior:

The Produce button should be enabled after copying a message, similar to when directly producing to a topic.

Environment:

• AKHQ Version: 0.25.1
• Previous Version: 0.24.0
