Website editors setting up AI live chat can now more easily choose existing internal pages when adding links. This improves usability by showing relevant page suggestions instead of requiring manual URL entry.

Before this commit, the website URL picker used `autocompleteWithPages` to suggest internal links.

This commit removes the WebsiteUrlPicker and patches the BuilderUrlPicker to use the autocomplete component, enabling internal link suggestions for existing pages.

The server action form no longer shows the “Usage” field, reducing clutter for users configuring automated or manual actions. This makes the setup screen easier to understand without changing the underlying action behavior.

This change makes the color picker tab components available for extension across the editor, website, and web interface. It helps developers customize color selection behavior more safely without changing core code, with no direct impact on everyday users.

Since the [1] color picker tabs are plugable, and so, in order to be able to patch them, we'd need to export them. This commit exports them all at once.
