feat(StatusChatListCategory): introduce flag to show/hide buttons

This commit introduces a `showActionButtons` flag that defaults to `false`
and can be used to render the action buttons provided in the chat list category.

This is useful for cases where only admin users should have the right to
create channels inside categories or mutate a category's state.

Settings `showActionButtons: true` will then render the buttons.

Closes #150
