Subject: [PATCH] Initializes Fava client on startup

Initializes the Fava client with default settings when the Castle extension starts.

This ensures the client is ready to interact with Fava immediately and provides feedback if Fava is not configured correctly.

The client is re-initialized if the admin updates settings later.
