UX: Ambiguous error message in editor when a provider is blocked by Connector Approvals #660

Description
When an AI request (such as title generation) is blocked by the Connector Approvals feature, the error message displayed in the block editor is ambiguous and misleading. It suggests that no provider is connected or that the connected provider doesn't support the feature, rather than guiding the admin to approve the pending request.

Steps to Reproduce

• Install the AI plugin and a provider plugin (e.g., AI Provider for Google).
• Configure the API connection but do not approve the caller yet in the "Connector Approvals" screen.
• Open a page/post and attempt to use an AI feature, such as "Generate Title".
• Observe the red error notice at the top of the editor.

Current Behavior
The editor displays the following error notice:

"Title generation failed. Please ensure you have a connected provider that supports text generation."

This leads the user to believe their API keys are invalid, that the connection failed entirely, or that the chosen model doesn't support text capabilities.

Expected Behavior
Since the provider is connected but simply awaiting administrator authorization, the error message should be context-aware.

It should explicitly mention that the connector requires approval and, if possible, provide a direct link to the approval page (/wp-admin/tools.php?page=connector-approvals).

Suggested copy:

"Title generation failed. The AI connector is currently pending authorization. Please approve the request under Tools > Connector Approvals."
